Paralyze Ray

The Paralyze Ray is one of twelve different magical energy eye ray capabilities that are created and used by Beholders and other similar aberrations. It is a common and frequently projected attack ray released by most types of beholders encountered during adventuring. It is primarily directed at summoned creatures, occasionally with an added Death Spell.
Death Tyrants and Gauth will also use it against any party member with the least amount of damage (DT-HPGT 35; G-HPGT15).
Gauth will use it against any party member but not against summoned creatures.
Spectators will use it against any helpless party member (HPGT 35) but not against summoned creatures.
Directors, the Elder Orb in The Planar Sphere, and the Unseeing Eye do not release this eye ray.
The eye ray is similar to the innate Paralyze ability used by Tanar'ri and the Paralyze charge ability available with the Eyes of the Beholder.
