Psychics at 6th cast it as a 3rd level spell.
All others cast it as a 3rd or 5th level spell at 7th level.
Capped at 24HD worth of creatures.
Does this target 24HD worth of creatures, or does it target until 24HD have failed? I think the former.
Does it target nearest first or farthest first?
Does it target weakest first or most powerful first?
Does not say it doesn't affect you. If you fail the save for yourself, you can no longer concentrate on the spell to keep it going.
RAI, I think you don't target yourself.
Doesn't say it doesn't affect allies.
I would suggest getting Selective Spell, except that only affects instant spells.
I also think this is best used vs. mooks while your party is far away.
It can also be used to gather scattered creatures.
