Raining Rubble CR 9
Type magical; Perception DC 33; Disable Device DC 33
Trigger visual; Reset automatic (1d4+2 rounds)
Effect 20 ft.-square area explodes with rubble from a nearby wall (3d6+4; DC 22 Reflex for half damage). When raining rubble resets, the section of exploded wall rebuilds itself, dealing the same damage to any creatures still in the area
When a member of one of the Orders of Timeaus walks nearby (or a member of the Banlan Brotherhood activates it) a rune inscribed on the wall explodes, showering the area with rubble; a few rounds later the trap casts mend to reform itself. Originally used by the people of Timeaeus to do repairs on the Nyamo Wall, it was later adopted by the Banlan Brotherhood for guerrilla warfare against the Orders.
