- This page details a weapon with special rules for enhancing and using its magic properties; for more information, see Ray Weapons in Eberron.
Summary::Developed in the conflict of the Last War as a counter to enemy spellcasters, an ''essence disruptor'' is a potent antimagical weapon, a bulkily constructed ray weapon of cold iron. An essence disruptor fires a beam of pure white light, a ray with a range of 40 ft. Any spellcaster or artificer hit by the beam loses one random prepared spell, spell slot, or infusion of the highest level they can cast. A psionic character hit by the beam loses a number of power points equal to their manifester level.
