You have found the entrance to the Dungeon of Umslopagaas of the Shiny Teeth, otherwise known as the Deathtrap Equalizer Dungeon! Anyone with less than 5 levels and 70 combat adds may enter this dungeon.
You are travelling through a hilly region. You have a 1 in 6 chance of a random encounter from the table at 75.
You have found the Riddling Tree. Will you undertake its challenge? If you can succeed at a level 3 Intelligence saving throw it gives you a reward:
1-2 Random jewel
3-4 Random magic item (See T&T Bonus Pack #1)
5-6 Add +1d6 to a random ability score
If you fail, determine your penalty:
1-2 Teleported into a random Deathtrap Equalizer challenge. If you survive, you return to a random overland map location.
2-3 Lose 1d6 from a random ability score
4-6 You are turned into a nasty little gremlin rogue (undo kin bonuses and apply those of a gremlin, class benefits change as well).
You may only challenge the Riddling Tree once.
