There are many different formulae and calculations and interesting data in Tibia. For example how much experience you need for a level, how much mana you need for a magic level, how long time it takes to advance in different skills, how long time a day in Tibia is counted in real life time, etc etc.

## Character Statistics

### Experience

For the amount of experience needed to reach a certain level:

$\frac{50lvl^{3}}{3} - {100lvl^{2}} + \frac{850lvl}{3} - 200$

$= \frac{50\left(lvl-1\right)^{3} - 150\left(lvl-1\right)^{2} + 400\left(lvl-1\right)}{3}$

For the amount of experience needed to reach the next level:

$50lvl^{2} - 150lvl + 200$

### Skills

All the skills advance using the same base formula with different parameters. Skill advance is based on skill points, which are mana points used for Magic Level, hits for Melee, Distance Fighting and Shielding and attempts for Fishing. The general formulae are:

Points required to advance to next skill level:

$P = A \cdot b^{skill - c}$

Total points at a certain skill level:

$Tp = A \frac{b^{skill - c}-1}{b-1}$

where,

• $A$ = skill constant,
• $b$ = vocation constant,
• $c$ = skill offset;

The skill offset is the starting skill. It's $0$ for Magic Level and $10$ for all other skills.

The skill constants are the same for all vocations. They are as follows:

Skill Constants (A)
Skill Constant
Magic Level 1600
Melee skills 50
Distance Fighting 30
Shielding 100
Fishing 20

Since a character can block up to two creatures using a Shield at a time, in ideal training scenarios the Shielding constant is the same as the Melee constants. For Offline Training, however, it does make Shielding training half the rate of Melee training.

The vocation constants change for each vocation and each skill. The higher the constant, the higher the amount of points needed to advance to the next skill level. They are as follows:

Vocation Constants (b)
Vocation Magic Axe/Club/Sword Fist Distance Shielding Fishing
None 4.0 2.0 1.5 2.0 1.5 1.1
Knight 3.0 1.1 1.1 1.4 1.1 1.1
Paladin 1.4 1.2 1.2 1.1 1.1 1.1
Sorcerer 1.1 2.0 1.5 2.0 1.5 1.1
Druid 1.1 1.8 1.5 1.8 1.5 1.1

For example, this is the mana spent required for a Druid or Sorcerer to advance to the next Magic Level:

$P = 1600 \cdot 1.1^{mlvl-0}$

And the total mana used at a certain Magic Level:

$Tp = 1600 \frac{1.1^{mlvl-0}-1}{1.1-1}$

Similarly, for a Knight training a Melee skill, we have:

$P = 50 \cdot 1.1^{skill-10}$

$Tp = 50 \frac{1.1^{skill-10}-1}{1.1-1}$

### Mana Training Time

This formula enable you to calculate how much time is needed to go a Magic Level up.

$y = a \cdot b^x \cdot z$

$y$ is the time needed to go a Magic Level up, in hours;
$x$ is the current Magic Level;
$z$ is the percent you have to go to the next Magic Level in decimal form (i.e. $47\% = 0.47$).
$a$ is the Vocation factor, depending on Mana regeneration:

$a = \frac{1600}{\left(\text{MP per second}\right) \cdot 3600} = \frac{4}{9} \cdot \frac{1}{\left(\text{MP per second}\right)}$

• Mages: $a = \frac{2}{3}$
• promoted Mages: $a = \frac{4}{9}$
• Knights and Elite Knights: $a = \frac{4}{3}$
• Paladins: $a = \frac{8}{9}$
• Royal Paladins: $a = \frac{2}{3}$

### Magic Power

$\max\left(1,\frac{lvl+4 \cdot mlvl}{100}\right)$
Usually displayed as percent.

### Hitpoints, Mana and Capacity

Vocation Hitpoints Mana Capacity
Per Level Total Per level Total Per level Total
Paladins $10$ $5\left(2lvl + 21\right)$ $15$ $5\left(3lvl - 6\right)$ $20$ $10\left(2lvl + 31\right)$
Knights $15$ $5\left(3lvl + 13\right)$ $5$ $5\left(lvl + 10\right)$ $25$ $5\left(5lvl + 54\right)$
Sorcerers and Druids $5$ $5\left(lvl + 29\right)$ $30$ $5\left(6lvl - 30\right)$ $10$ $10\left(lvl + 39\right)$
Rookies $5$ $5\left(lvl + 10\right)$

What is worth noting, Rookies gain the lowest possible values per level among all vocations.

$HP + MP + Cap = 5\left(9lvl + 77\right)$

Sum of HP, MP and Cap does not depend on vocation, providing balance between them (assuming, of course, they are each desired equally, which is often not the case).

### Speed

Note that spells like Haste and Strong Haste increase your base speed without items and mount, you have to add the speed of the extra items and mount only after calculate your base speed with the spells.

Your speed helps determine how fast you walk in-game. The base speed for a level $1$ player is $110$.

The type of surface you walk on reduces your speed (i.e. you walk faster on pavement than you do on grass or mud). Below are the formulae for determining your speed in different states.

#### Unmodified

$109 + Level$
This determines your Unmodified Speed, or "BaseSpeed". The modifiable speed value, however, is equal to $BaseSpeed-40$. This is important when dealing with multiplicative buffs and debuffs such as speed spells.

#### Walking Time

The number of seconds it takes for a player to walk 1 square

$\,=\frac{Tile Walking Time}{Player Walk Speed}$

Walking Time is entirely dependent on the type of Tiles you are walking on. Moving on a diagonal takes 2 times as long.

#### Haste

$(BaseSpeed-40) \cdot 1.3 + 40$

This determines the difference in your speed after casting Haste. It replaces any other haste spell.

#### Strong Haste

$(BaseSpeed-40) \cdot 1.7 + 40$

This determines the difference in your speed after casting Strong Haste. It replaces any other haste spell.

#### Swift Foot

$(BaseSpeed-40) \cdot 1.8 + 40$

It replaces any other haste spell.

#### Charge

$(BaseSpeed-40) \cdot 1.9 + 40$

It replaces any other haste spell.

$(BaseSpeed-40) \cdot 2.5 + 40$

It replaces any other haste buffs.

### Prey System

#### Timer Deductions

All bonuses have specific triggers upon which time is deducted from the remaining time of a prey bonus. Much like stamina, time is deducted based on the recent activity of the player. The amount of time deducted is equal to:

$D(currentTime,\ lastTriggerTime) = min(currentTime\ -\ lastTriggerTime,\ 2\ minutes)$

Where:

currentTime is the current system time. This is used to compute time relative to the last trigger time.
lastTriggerTime is the system time of the last relevant trigger event. The lists of relevant trigger events for each bonus type are listed below.

The triggers that are used to deduct time depend on the specific bonus. For example, when the user takes damage, the timer for damage reduction will be affected, but not the timer for experience gain. These triggers act on any event of the specified type, not just ones that would be affected. For example if an increased loot bonus is active for killing Rats, killing a Spider will affect the timer even though Spiders do not provide bonus loot. The triggers for each type of bonus are as follows:

Damage Reduction: time is deducted when:

• the user takes damage, whether PvP or PvE.
• the user gains experience from a slain creature.
• [NOT TESTED]: gaining experience from a quest or other non-combat event.

Damage Increase: time is deducted when:

• the user gains experience from a slain creature.

Loot Increase: time is deducted when:

• the user gains experience from a slain creature, irrespective of whether or not that creature has a corpse.
• [NOT TESTED]: gaining experience from a quest or other non-combat event.

Bonus Experience: time is deducted when:

• the user gains experience from a slain creature.
• [NOT TESTED]: gaining experience from a quest or other non-combat event.

#### Value and Effect

When bonuses are determined, two values are generated: the bonus type (damage increase, damage reduction, etc.) and bonus value. The effect of a bonus is a function of its value according to the following functions.

Damage Increase:

$E(value) = (5 + 2 \cdot value)%$

Damage Reduction:

$E(value) = (10 + 2 \cdot value)%$

Bonus Experience:

$E(value) = (10 + 3 \cdot value)%$

Improved Loot:

$E(value) = (10 + 3 \cdot value)%$
Bonus Minimum Step
Damage Increase (%) 5 2
Damage Reduction (%) 10 2
Bonus Experience (%) 10 3
Improved Loot (%) 10 3

Combining these formulas provides a generalized formula:

$E(value) = (minimum + step \cdot value)%$

Where:

minimum is the theoretical effect at value = 0 (equal to $E(1) - step\,$).
step is the effect's step. For each value, the effect increases step percent.

### Imbuing

#### Mana Leech

When one of the Void imbuements is triggered by area attacks, the mana leeched is not the same as it would be for one creature multiplied by the number of creatures, otherwise this imbuement would be too powerful. There are a few ways to calculate the actual mana gained. One way of looking at it is to consider that 100% of the leech is applied to one creature, and 10% of it to the other creatures, though this does not allow for an accurate calculation when different resistances are involved.

In reality, for each creature the mana leeched is the following:

$ManaLeeched = \frac{Dmg \times Leech \times (0.1N+0.9)}{N}$,

where N is the number of creatures attacked and Leech is the Leech % depending on the level of the imbuement (Basic, Intricate or Powerful). Furthermore, the result is always rounded up. For N = 1, this simplifies to:

$ManaLeeched = Dmg \times Leech$,

as one would expect.

Note1 that since the value is always calculated independently for each creature and rounded up, simply multiplying the first formula by N and consider the total damage dealt does not result in the total mana leeched and will underestimate the real value.

Note2,3 Damage prey do not influence the mana/health leech amount, crit hit does increase the leech. "Overkill" damage dealth above max health/current health of a monster still does count for leech.

## Tibian Environment

### Time

• 2.5 seconds = 1 Tibian minute
• 30 minutes = 12 Tibian hours
• 1 hour = 24 Tibian hours

### House Rent This article or section is deprecated.The information on this page is no longer relevant to the Tibia or TibiaWiki community. It may have been removed from the game or made inaccessible.The information in this page or section may not be accurate anymore, but this page should be retained for posterity.discuss

The following section refers to the house rent formula used up to April 15, 2019.

The formula for determining house rent is:

$rent = 100\left(\max\left(b, 1\right) - 1\right) + r \cdot s + f$

Where:

• $f$ is furnishing value. Most houses do not have one ($f = 0$), but some houses such as House of Recreation have one (in this case $f = 5000$).
• $b$ is the number of beds.
• $r$ is rate, the gp/sqm rate. Usually this is an increment of 5 gp/sqm.
• $s$ is size, the amount of tiles in the house.

Example 1: Darashia 5, Flat 01 - 25 sqm, 1 bed, 0 furnishing value.

$rent = 100\left(1 - 1\right) + 25r + 0$
$rent = 25r$

To find the other value, use either the rent or the rate. Since the rent is readily available:

$1000 = 25r$
$r = 40$

Thus the rate is 40 gp/sqm.

Example 2: Rathleton Plaza 2 - 56 sqm, 2 beds, 0 furnishing value.

$rent = 100\left(2 - 1\right) + 56r + 0$
$rent = 100 + 56r$

To find the rent, you can also plug in the rate (if known), which is 45 gp/sqm.

$rent = 100 + 56 \cdot 45$
$rent = 2620$

### Spell/Rune Damage/Healing

NOTE: These formulae are based upon observed values after update 8.1.
All the spells have the same basic formula: $\lfloor lvl \cdot 0.2 \rfloor + \left(mlvl \cdot x\right)+y$, where $x$ is a decimal number and $y$ is an integer.
For PvP damage, just divide the final result by $2$.

Healing spells:
Light Healing
Max healing: $x = 1.795, y = 11$
Min healing: $x = 1.4, y = 8$
Intense Healing
Max healing: $x = 5.59, y = 35$
Min healing: $x = 3.184, y = 20$
Wound Cleansing
Max healing: $x = 7.95, y = 51$
Min healing: $x = 4, y = 25$
Mass Healing
Max healing: $x = 10.43, y = 62$
Min healing: $x = 5.7, y = 26$
Ultimate Healing
Max healing: $x = 12.79, y = 79$
Min healing: $x = 7.22, y = 44$

Instant attack spells
Strike spells
Max damage: $x = 2.203, y = 13$
Min damage: $x = 1.403, y = 8$
Divine Missile
Max damage: $x = 3, y = 18$
Min damage: $x = 1.79, y = 11$
Ice Wave
Max damage: $x = 2, y = 12$
Min damage: $x = 0.81, y = 4$
Fire Wave
Max damage: $x = 2, y = 12$
Min damage: $x = 1.25, y = 4$

Rune attack spells
Light Magic Missile
Max damage: $x = 0.81, y = 4$
Min damage: $x = 0.4, y = 2$
Heavy Magic Missile/Stalagmite
Max damage: $x = 1.59, y = 10$
Min damage: $x = 0.81, y = 4$
Icicle/Fireball
Max damage: $x = 3, y = 18$
Min damage: $x = 1.81, y = 10$
Holy Missile
Max damage: $x = 3.75, y = 24$
Min damage: $x = 1.79, y = 11$
Sudden Death
Max damage: $x = 7.395, y = 46$
Min damage: $x = 4.605, y = 28$
Thunderstorm/Stone Shower
Max damage: $x = 2.6, y = 16$
Min damage: $x = 1, y = 6$
Avalanche/Great Fireball
Max damage: $x = 2.8, y = 17$
Min damage: $x = 1.2, y = 7$

These spells have not been tested by me (yet) so I'll leave the old formulae here.
NOTICE: These formulae are based upon observed values with c calculated to one tenth with fair certainty
min: $\frac{lvl}{5} + mlvl \cdot c$
max: $\frac{lvl}{5} + mlvl \cdot d$
avg: $\frac{max+min}{2} = \frac{lvl}{5} + \frac{mlvl(c+d)}{2}$

* c = Multiplier for min of the desired attack spell/rune
* d = Multiplier for max of the desired attack spell/rune
The c values are roughly:

0 for Explosion [adevo mas hur] (note: the min damage of this spell is 0).

2.5 for Energy Beam [exevo vis lux]

4 for Great Energy Beam [exevo gran vis lux]

4 for Divine Caldera [exevo mas san]

3.5 for Terra Wave [exevo tera hur]

4.5 for Energy Wave [exevo vis hur]

10 for Heal Friend [exura sio]

5 for Rage of the Skies [exevo gran mas vis]

7 for Hell's Core [exevo gran mas flam]

5 for Wrath of Nature [exevo gran mas tera]

6 for Eternal Winter [exevo gran mas frigo]

18.5 for Divine Healing [exura san]

The d values are roughly:

4.8 for Explosion [adevo mas hur]

4 for Energy Beam [exevo vis lux]

7 for Great Energy Beam [exevo gran vis lux]

6 for Divine Caldera [exevo mas san]

7 for Terra Wave [exevo tera hur]

9 for Energy Wave [exevo vis hur]

14 for Heal Friend [exura sio]

12 for Rage of the Skies [exevo gran mas vis]

14 for Hell's Core [exevo gran mas flam]

10 for Wrath of Nature [exevo gran mas tera]

12 for Eternal Winter [exevo gran mas frigo]

25 for Divine Healing [exura san]

### Melee

NOTICE: This formula is based upon observed values.

• Minimum Damage:

$Minimum Damage = \frac{lvl}{5}$

• Maximum Damage:

$Maximum Damage = 0.085 \cdot d \cdot atk \cdot skill+\frac{lvl}{5}$ Where:

• $atk$ = Weapon's attack
• $d$ = Damage Factor:
• Full Attack: $1$
• Balanced: $0.75$
• Full Defence: $0.5$
• Let's take for example a player level 80, holding a weapon which has an attack value of 50, skills of 85 and he is attacking on full attack.
• It would be like this: $\left(0.085 \cdot 1 \cdot 50 \cdot 85\right) + \frac{80}{5} = 377.25$ (377 rounded)
• Damage factor

So the damage you will do will be between 0 and the calculated number, please note that shielding and armor from the target will reduce your damage. The average damage you will deal is approximately half your maximum damage. Also note, this doesn't take into account monsters weakness or strength to physical damage and if you use blood rage, you'll have to use the appropriate skills in place of your normal skills.

#### Melee based spells

NOTICE: This formula is based upon observed values.

• atk = Weapon's attack

min: $\frac{skill+atk}{3} + \frac{lvl}{5}$

max: $skill + atk + \frac{lvl}{5}$

avg: $\frac{max+min}{2} = \frac{2}{3}(skill + atk) + \frac{lvl}{5}$

min: $0.5\left(skill + atk\right) + \frac{lvl}{5}$

max: $1.1\left(skill + atk\right) + \frac{lvl}{5}$

avg: $\frac{max+min}{2} = 0.8\left(skill + atk\right) + \frac{lvl}{5}$

min: $0.5\left(skill + atk\right) + \frac{lvl}{5}$

max: $1.5\left(skill + atk\right) + \frac{lvl}{5}$

avg: $\frac{max+min}{2} = skill + atk + \frac{lvl}{5}$

min: $1.1\left(skill + 2 \cdot atk\right) + \frac{lvl}{5}$

max: $3\left(skill + 2 \cdot atk\right) + \frac{lvl}{5}$

avg: $\frac{max+min}{2} = 2.05\left(skill + 2 \cdot atk\right) + \frac{lvl}{5}$

Note: As usual, damage is reduced by armor but none of these abilities can be blocked by shielding. Also note, this doesn't take into account monsters weakness or strength to physical damage and if you use blood rage, you'll have to use the appropriate skills in place of your normal skills.

### Distance

NOTE: These formulae are based upon observed values.

• Minimum Damage:

$Minimum Damage = \frac{lvl}{5}$

• Maximum Damage:

$Maximum Damage = 0.09 \cdot d \cdot skill \cdot atk + Minimum Damage$

• $atk$ = Weapon's attack
• $d$ = Damage Factor:
• Full Attack: $1$
• Balanced: $0.75$
• Full Defence: $0.5$

To calculate your damage in PvP, divide the result by $2$.

Note that armor of the target will reduce your damage.

• Chance to hit (without weapon hit chance modifier)
 Distance 1H weapon (throwing) 2H weapon (any bow or crossbow) Any bow + Sniper Arrows 1 $\min\left(75, \left( DistSkill + 1\right)\right)%$ $\min\left(90, \left(1.2 \cdot DistSkill + 1\right)\right)%$ $\min\left(100, \left(1.35 \cdot DistSkill + 1\right)\right)%$ 2 $\min\left(75, \left(2.4 \cdot DistSkill + 8\right)\right)%$ $\min\left(90, \left(3.2 \cdot DistSkill \right)\right)%$ $\min\left(100, \left(3.2 \cdot DistSkill + 5\right)\right)%$ 3 $\min\left(75, \left(1.55 \cdot DistSkill + 6\right)\right)%$ $\min\left(90, \left(2 \cdot DistSkill \right)\right)%$ $\min\left(100, \left(2.25 \cdot DistSkill + 2\right)\right)%$ 4 $\min\left(75, \left(1.25 \cdot DistSkill + 3\right)\right)%$ $\min\left(90, \left(1.55 \cdot DistSkill \right)\right)%$ $\min\left(100, \left(1.5 \cdot DistSkill + 2\right)\right)%$ 5 $\min\left(75, \left( DistSkill + 1\right)\right)%$ $\min\left(90, \left(1.2 \cdot DistSkill + 1\right)\right)%$ $\min\left(100, \left(1.35 \cdot DistSkill + 1\right)\right)%$ 6 $\min\left(75, \left(0.8 \cdot DistSkill + 3\right)\right)%$ $\min\left(90, \left( DistSkill \right)\right)%$ $\min\left(100, \left(1.2 \cdot DistSkill - 4\right)\right)%$ 7 $\min\left(75, \left(0.7 \cdot DistSkill + 2\right)\right)%$

#### Distance based spells

NOTICE: This formula is based upon observed values.

min: $\frac{skill + 25}{3} + \frac{lvl}{5}$

max: $skill + 25 + \frac{lvl}{5}$

avg: $\frac{max+min}{2} = \frac{2}{3}\left(skill + 25\right) + \frac{lvl}{5}$

### Armor

Note that:

• Armor reduction will only apply when damage crosses the shield.
• The damage armor needs to reduce may be lower than original damage because of the shield reduction.
• If you get a negative number as armor reduction, it means 0.
• Floor function is used here, basically it means that we remove decimals.
• Ceil function is used here, basically it means that we round up numbers with decimals to next integer.

Variables:

• r = minimum armor reduction
• R = maximum armor reduction
• t = total armor
• d = damage (after the shield)
• p = percentage reduction of item

#### Armor Reduction

$r = \left \lfloor \frac{t}{2} \right \rfloor$

$R = \left \lfloor \frac{t}{2} \right \rfloor \cdot 2 - 1$

where $\left \lfloor x \right \rfloor$ denotes floor function (rounding down).

#### Percentage Reduction

This formula have to be applied for every single item that has percentage reduction.

$d = \left \lfloor \frac{100 - p}{100} \cdot d \right \rfloor$

#### Example

You get a hit with original value of 200 wearing only Zaoan Helmet and Protection Amulet

t = total armor = 9
$r = \left \lfloor \frac{9}{2} \right \rfloor$
r = 4
$R = r \cdot 2 - 1$
R = 7

Now we calculate the % reduction that Zaoan Helmet has

p = 5
$d = \left \lfloor \frac{100 - 5}{100} \cdot 200 \right \rfloor$
d = 190

Now we calculate the % reduction that Protection Amulet has

p = 6
$d = \left \lfloor \frac{100 - 6}{100} \cdot 190 \right \rfloor$
d = 178

For this example, damage becomes 178, minimum armor reduction will be 4 and maximum armor reduction will be 7, so the hit will hit you from 171 to 174.

### Armor and Defense

• Damage reduction

Min:

$totalArmor \cdot 0.475$

Max:

$totalArmor \cdot 0.95 -1$

• Attack of Creature = a

(Let's supose that a creature has a max damage of 500. The attack of creature will be a random number from 1 to 500)

• Defense = b (Defense value of your shield plus your weapon modifier or defense value of your two handed weapon)
• Total Armor = c (Make a sum of all your set arm value)
• Shielding = d
• Defense factor = e

Full Attack: 5
Balanced: 7
Defensive: 10

Now use this formula:

$a - b \cdot d \cdot \frac{e}{100} - \frac{a}{100} \cdot c = averageDamage$

NOTICE: The max damage of a creature could be higher than the max damage in creatures page.
