The halt undead spell says:
"This spell renders as many as three undead creatures immobile. A nonintelligent undead creature gets no saving throw; an intelligent undead creature does. If the spell is successful, it renders the undead creature immobile for the duration of the spell (similar to the effect of hold person on a living creature). The effect is broken if the halted creatures are attacked or take damage."
Would an undead get a new save each round, like the hold person spell?
I would assume so, but I guess it could be interpreted that the target is immobile for the duration of the spell.. with no surther save.
Thoughts?
