1. It electrifies just enough to hold your hand tight and inflict 1 point of electricity damage per round.
2. Your hand sticks to it … you just grabbed a mimic, buddy.
3. It comes out of the wall with a shower of sparks.
4. Your fingers tingle and then begin changing to stone (save vs. petrification); if this save fails, it begins to affect your arm (another save), etc.
5. Loud bells begin ringing, shaking dust from the ceiling and alerting all monsters on the level to your presence; some come running for a free-for-all, while others begin setting traps.
6. The floor opens beneath you (10-ft. pit; 50% chance of spikes; 25% chance of water; 10% chance of a crocodile; 5% chance of 4 skeletons; 1% chance of a magic item).
7. The floor opens beneath you (chute down to next dungeon level).
8. The ceiling opens above you, water pours down (1d4 damage).
9. The ceiling opens above you, green slime pours down.
10. The wall falls down, revealing a treasure room.
11. The wall falls down, revealing a clutch of rust monsters.
12. The walls falls down … on you (save or crushed for 2d10 damage).
13. Iron walls rise from the floor to block all exits, poisonous gas begins filling room.
14. You teleport to a random location on this dungeon level.
15. You teleport to a random location on a lower dungeon level.
16. You teleport back to the surface.
17. The room makes a 180-degree turn (save or knocked prone on floor); you are now in a mirror universe.
18. You gain the ability to use one random 1st level magic-user spell, one time. On a second pull, you gain a spell, but only if it can be plucked from the mind of a comrade. On a third try, you lose any spells you had memorized/prepared. On a fourth try, you summon a marilith demon, because seriously, how many damn times are you going to pull this lever?
19. You change into a random animal with as many hit dice as you have levels; your own mind is submerged beneath the psyche of the beast; this change lasts for 10 minutes.
20. You turn off all lights in the room (torches, light spells, etc.) off; pulling again reverses this.
I know, been a while. Very busy at work, also busy writing NOD Companion and Action X – which don’t lend themselves to excerpts just yet. I have a few posts planned for this week, though, so hang in there with me.
