When you manifest this power, you cause the clothing or armor of affected creatures to constrict and bind them. Each round, an affected creature takes 1d4 points of damage and a cumulative —1 penalty on attack rolls. Additionally, arcane spells that have somatic components have a cumulative 5% chance of spell failure per round if cast by an affected creature (this stacks with any exist ing chance of spell failure). A successful Fortitude save negates the damage, the penalty on attack rolls, and the chance of spell failure for that round.
Affected creatures can attempt to doff their clothing or armor, but must make a successful DC 18 Strength check or a DC 18 Escape Artist check to do so. Removing normal clothing requires two full-round actions; for removing armor, see Donning Armor (PH 123).
Clothing and armor is not damaged by constrictor's touch. However, if successfully removed, armor and cloth ing cannot be put on again until the power's duration has expired.
