Wondrous Item, artifact (requires attunement by a Has to have been to heaven and been revered by an arch angel either during or berfore the campain)
You can use an action to blow this horn. In response, 3d12+2 warrior angels appear within 60 feet of you. Each roll of the d12 counts as a single angel and add three to each roll. They use the statistics of a berserker. They return to heaven after 1 hour or when they drop to 0 hit points. Once you use the horn, it can't be used again.
Notes: Language: Aarakocra, can only use on the first turn of interaction., Has to have been to heaven and been revered by an arch angel either during or berfore the campain, Summoning
It is purely for fun, dont remove plz
Sounds like something you would use in a most desperate hour only. Pretty nice.
You need to fix or clarify your 2nd and 3rd line describing the rolls and effects. From what I can tell, this is an amped up version of the Horn of Valhalla, but with a 1 shot use. That's not bad at all, it's great for preventing abuse. No idea what's going on with the Language: Aarakocra though. It really doesn't need that, or all the attunement description. I'd recommend putting at the top something like this:
An otherworldly artifact, resonant only with those who have earned the favor of the god or gods associated with this instrument.
