[Ultimate Magic] Interrogation spell

[Ral' Yareth]

"School necromancy [evil, pain]; Level inquisitor 1, sorcerer/
wizard 1, witch 1"

"You question the target, backed up by the threat of magical
pain. You may ask one question per two caster levels."

The way it is written, this spell would be useless for a 1st level character. Should it allow 1 question at first level + 1question/2levels?

Suggestions?

I have the same exact question and this hasn't been addressed. Would like to look into picking it up for this PFS character but don't want to do so if it's not going to be useful for another level.

Probably the text misses (minimum 1 question) note that is common in case of "once per two levels" abilities that are available for 1st level characters.
