Cassisians

[JosMartigan]

Cassisian Angels - NG Small outsider (angel, extraplanar, good). A cassisian’s true form is a helmet possessing a pair of bird’s wings. The exact style of helmet varies by the deity the angel serves.

Could (or would) a cassisian serve as helmet for another creature? If so, would that effect the creature or the wearer in adverse ways?

The description says nothing about the interior of the angel being full of something (energy?) that would prevent a creature from wearing it if the cassisian was not opposed to the idea.

I can think of no reason for most creatures to be adversely affected by wearing an angel as a helmet. A cassisian is certainly physically capable of serving so; whether they're willing is entirely up to the GM.

I'd think it could be worn.

But as helmets seem to serve no statistical benefit whatsoever (so that's why people never wear them in situations where they should), and the Cassisian would be rendering himself unable to move for the interim, there would be little reason for one to subject itself to such a dehumanizing (deangelizing?) fate.

The Cassisian actually gives AC and save bonuses to one creature within 5 feet. So assuming that the Cassisian wants to assist the person (they are an Improved Familiar choice) it gives the Cassisian a way to protect its handler while also looking inconspicuous so as to avoid being attacked.
