Busine of Divine Reinforcements

ITEM 15
Price 6000 gp
Usage held in 1 hand
Bulk —

This long, straight, trumpet-like instrument is made of well-polished brass and adorned with imagery of angels fighting demons or religious symbols. When played as an instrument, the busine generates powerful and harmonious notes and grants a +2 item bonus to Performance checks.

Frequency once per minute
Effect You play a few notes on the busine. Evil creatures within 60 feet who hear the notes must succeed at a DC 34 Will save or be Stunned for 1 round, or 2 rounds on a critical failure; this is an incapacitation effect.

Activate command, envision, Interact
Frequency once per day
Effect You blow into the busine and conjure a celestial with the effects of a 6th-rank 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-rank summon celestial spell instead, meaning the celestial will fight any creature, not just evil creatures, and will perform other tasks as you command.
