The Paradox Tower Quest/Spoiler

Required Items

 * 4 Skulls
 * Machete or Heavy Machete
 * Melon, Banana, Cherry, Apple, Grapes, and Coconut

Method

 * Key 3899 to the tower is north of paradox tower in a dead tree, you need to go though Minotaur caves to get to it passing directly under the tower itself. The tree is booby trapped so you might lose 200hp and Poison Fields may block your path when you go to leave the tree (this trap is not always triggered).
 * Use Levitate spell or parcels to get climb up the "stairs" on the mountain.
 * When you come across 4 sacrifice stones, place one skull on each stone and walk to the teleport spot in the middle - you will be teleported to the tower.
 * Go north and cut down all of the Jungle Grass. When the grass starts to grow back, step on the switch plate in the corner. The big stone will turn into a staircase.
 * The next room will have a series of levers - they need to be in the following directions (from left to right): Right, Right, Left, Left, Right, Left
 * The next room will have a Ghoul behind some Magic Walls. Flip the switch and a box will appear with the ghoul. Wait until the ghoul pushes the box into the north corner of his area, and a ladder will appear. Go up the ladder.
 * In this room you will need to use key 3899 that you got from the dead tree.
 * After opening the door, sacrifice the fruit in the following order (from left to right): melon, banana, cherry, apple, grapes, coconut.
 * There will be two statues on the far wall. Place the black and white knight chess pieces on the correct sides and pull the lever.
 * Here you will meet the riddler in the paradox tower. Say to him "Hi", "Test", "Yes", "Goshnar", "Demonbunny".
 * The 3rd question he asks you is fake. When he asks it, jump back to the teleport. If you answer the question, you will be wrong and get sent to Hellgate
 * Now you need to visit some other NPCs:
 * Edowir (south of Thais)
 * Say "Hi", "Hugo", "Plains of Havoc", "Bye"
 * Oldrak (in Plains of Havoc temple)
 * Say "Hi", "Hugo", "Myth", "Yenny the Gentle", "Bye"
 * Zoltan (on Edron)
 * Say "Hi", "Yenny the Gentle", "Crunor's Caress", "Bye"
 * Puffels (on Edron)
 * Say "Hi", "Hugo", "Beast", "Bye"
 * Padreia (Druid Guild in Carlin)
 * Say "Hi", "Crunor's Caress", "Footnote", "Bye"
 * Lubo (North of Thais, South of Mount Sternum)
 * Say "Hi", "Crunor's Cottage", "Flower Guys", "Accident", "Stable", "Bye"
 * Go back to the Paradox Tower, and talk to the Riddler again. He will ask different questions. Say to him "Hi", "Sigil", "Yes", "Goshnar", "Demonbunny", "Tha'kull", "Yes", "Breath", "Silence", "Old", "Yes", "Green", "None"
 * Don't answer the last question again, or you will be sent to Hellgate, again.
 * Now you need to go talk to another NPC. Go to Mintwallin and talk to the npc prisoner. Say "Hi", "1+1", "Yes", "Green", "Yes"
 * the prisoner will tell you what "1+1" equals - this is apparently different for each player, so be sure to remember the number he tells you.
 * Only answer "Green" (as above) if he asks you for his favorite color. He sometimes does not ask this question.
 * Go back to the Paradox Tower and talk to the riddler again. Say "Hi", "Test", "Yes", "Goshnar", "DemonBunny", "Tha'kull", "Yes", "Breath", "Silence", "Old", "Yes", "Green", "None", "your number"
 * After that you will be allowed into the treasure room. In the treasure room, there are two rows of switches on the floor. Which of these switches you walk over determines what rewards you get. Each switch will REMOVE one of the rewards for you.

K = 10k gp W = Wooden Wand (Quagmire Rod since the update, unless quest reward was changed) T = 32 Talons E = Phoenix Egg

[ K ][ W ][ T ][ T ][ T ][ E ] [ E ][ E ][ E ][ K ][ W ][ W ]

Therefore, if you walk straight up the far left, your rewards will be Wooden Wand and 32 Talons (K and E removed).
