DESCRIPTION
This spell allows you a degree of control over an undead creature. If the subject is intelligent, it perceives your words and actions favorably (treat its attitude as friendly). It will not attack you while the spell lasts. You can give the subject orders, but you must win an opposed Charisma check to convince it to do anything it wouldn’t ordinarily do. Retries are not allowed. An intelligent commanded undead never obeys suicidal or obviously harmful orders, but it might be convinced that something very dangerous is worth doing.

A nonintelligent undead creature gets no saving throw against this spell. When you control a mindless being, you can communicate only basic commands, such as “come here,” “go there,” “fight,” “stand still,” and so on. Nonintelligent undead won’t resist suicidal or obviously harmful orders.

Any act by you or your apparent allies that threatens the commanded undead (regardless of its Intelligence) breaks the spell.

Your commands are not telepathic. The undead creature must be able to hear you.

Thanks

Yes. Everyone can if you have enough uses of the ability. You can even reapply it endlessly leading up to the end of the last day of control, allowing permanent control over undead given enough time and castings.

SLAs take a standard action by default, not a free action. The mummy can still try it again and again, but only once per round.

Ah yes. I see where the NPC creation tool I use got it wrong.

It applied the "Constant" Spell-like ability rules.

Quote:

A spell-like ability usually has a limit on how often it can be used. A constant spell-like ability or one that can be used at will has no use limit; unless otherwise stated, a creature can only use a constant spell-like ability on itself. Reactivating a constant spell-like ability is a swift action.

Thanks for correcting me. Would've been embarrassing to make the mistake at the table. :-)
