Conditioning

This armor is cursed to steer the wearer towards evil, choking the life out of them every time they or one of their associates does a good action, reducing their Constitution by 2 each time, to a minimum of 1. Only committing an evil act can provide relief, removing the constitution penalty and giving 10 temporary hit points instead. Unequipping this armor is only possible after casting remove curse on the wearer and passing a DC 33 caster level check.
