A Xeg-Yi's touch sends a surge of anti-energy that causes 1d6+6 damage from massive cell death, as well as chilling touched materials. Every other round, a Xeg-Yi can also release a bolt of anti-energy that equals its touch at a range of 10 feet at a single target. The bolt chills metal and magic metal unless the owner succeeds in a save vs. lightning (11 for hard metal, 16 for soft metal, modifed by magic). A failed save results in 1d4 damage per segment of contact with the chilled metal. Xag-ya are affected by heat magic, disintegration, magic missiles, maces of disruption, and rods of cancellation, with no ill effects to the items involved. The shield spell defends against the attacks of a Xeg-yi, and a circle of protection will repel them. Abjure, alter reality, banishment, dismissal, dispel magic (treat at magic level of 2 x HD), holy word, limited wish, plane shift, or wish spells can slay or return the creatures to their home plane; all other magic or spells are useless. If a Xeg-Yi and a Xag-Ya should meet, they will rush together and destroy each other, releasing a 30' radius explosion doing 4d6+24 damage, with a save for 1/2 damage.

Slaying a Xeg-Yi will release a burst of negative energy that does 2d6+12 damage in a 10 foot radius, with the same metal chilling effect as a discharged bolt. Xeg-Yi also have some psionic prowess, but tend not to use them except to defend from psionic attacks. = HD per HD All/All = Int 120+10d6 Xeg-Yi, Trillochs, and Balhiir are the only denizens of the Negative Material Plane, and seem to be the only lifeforms that can thrive there. Xeg-Yi, although likely highly intelligent, seem mindless by human standards, but if met on the Negative Material Plane may respond to attempts at communication. Xeg-Yi may agree (1-4 on a 1d8) to act as a guide on the Negative Material Plane if the request is somehow communicated effectively. Xeg-Yi inhabit the Negative Material Plane, but sages surmise that they originated in a demi-plane elsewhere, later finding and thriving on the Negative Material Plane. Along with the Xag-Ya, a few wizards have also managed to conjure these creatures to use as guards for treasure, but the methods for doing so are not widely known. Xeg-Yi are very similar to the Xag-Ya, but the nature of this relationship has not yet been explored by sages in detail.
