Tyranteyes

This spell allows the caster to transform herself into a beholder until the spell expires or until she wills the magic to end. When this spell is cast, the caster vanishes and is transported to an extradimensional space, where she remains for one round while the spell forms a beholder body. During this round, she can cast any spell she has memorized, possesses the material components for, and can weave within one round. Typically, a defensive magic is wrought

A round after vanishing, the caster reappears as a beholder in the same spot she occupied when she disappeared. Her own body remains in the extradimensional space, unreachable by anyone. If the caster is slain in beholder-form, she is forever dead unless a contingency spell saves her. The contingency (as typically set up) causes the caster to reappear in her own body where the beholder was slain (this is not necessarily the same location from which the caster disappeared).

As a beholder, the caster has 69 hit points, is AC 0/2/7, moves at MV Fl 3 (B), and is in all other respects a normal beholder, with all the usual eyestalk powers. The caster's form corresponds in all respects to a living eye tyrant. Beholders are described fully in the Monstrous Manual Tome.

Damage suffered to the beholder body does not harm the caster's own body. If she ends the spell before it dies, she regains her own body with no damage at all. Once the caster decides to end the spell, the beholder disappears. In the following round, the caster reappears in the location she vanished from. The material component of this spell is part of a once living beholder.
