Effect You blow into the busine and conjure a celestial with the effects of a 6th-level Summon Celestial spell, but there are no alignment restrictions to define which celestials you can call. The celestial will fight only evil creatures and leaves after all present evil creatures have been defeated or the spell's duration ends, whichever comes first. You can Sustain the Activation to extend the spell's duration, as normal. If you have a deity and the conjured celestial's alignment is one of your deity's preferred alignments, the effect functions as a normal 6th-level summon celestial spell instead, meaning the celestial will fight any creature, not just evil creatures, and will perform other tasks as you command.
