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.

Sphere of Annihilation	29	Hazard	Lurker	DMG 93	A strange sphere of impenetrable blackness hovers before you.
