Imbuements: (Empty Slot).
The reflected damage cannot be greater than 1% of the maximum hit points of the attacker. That means, considering its damage reflection attribute of 42, it will reflect a maximum of 42 damage on creatures with 4200 or more health points.
This 1% limit must be respected even if the player is wearing more than one item with damage reflection. It can be exceeded though, if player uses Damage Boost Prey on a selected creature, so the maximal amount of damage reflection can be as high as 51-52 damage per turn.
The damage reflection is only triggered by melee damage. It doesn't affect the bosses. It is shown as a dark purple text.
