Kissing Maiden	4	Trap	Lurker	DMG2 66	When a square is entered, a section of floor slides aside and a stone post levers up to hit the creature in the square, pushing it back. The stone post then swings back down to reset the trap as long as the square is empty.

Death Strangler Statue	16	Trap	Blaster	DMG2 70	This statue is of a masked humanoid holding wicked-looking spiked chains in each hand. When a creature approaches, it comes alive, lashing out with its chains.
Elemental Tiles	16	Trap	Obstacles	DMG2 71	The area is riddled with floor tiles that transform before your eyes. At times, each tile resembles stone that ripples like water; then it transforms to boiling ice. Later the tile dances with a flame-colored mist that crackles before it grows into spikes of lightning. Whatever these tiles are, they don't look stable.

Pain Vault	20	Trap	Warder	DMG2 72	This highly complicated vault's lock looks like it's a pain to pick... and it is, in more ways than one.
Entropic Fissure	22	Hazard	Lurker	MotP 24	A shifting, writhing fold in reality churns in a mass of disgusting colors and abominable screams, whispers, and gurgles. It lurches toward you as if drawn by your living presence.
Life Eater Haze	22	Trap	Obstacle	DMG2 73	With a violent hiss, billows of blue-tinted purple gas fill the room. Each gasp of the vile stuff drains your strength and saps your life essence.

Maddening Mural	29	Trap	Warder	DMG2 74	A seemingly normal landscape is carved into the wall, but the more you look at it, the more you spot strange details. Images of vegetation hide eyes, mouths, and claws, and the shapes themselves start to twist into horrid monstrosities that reach out from the mural, lashing at your sanity.
Sphere of Annihilation	29	Hazard	Lurker	DMG 93	A strange sphere of impenetrable blackness hovers before you.
