Myrrh, Frankincense, and Steel: Kurald Galain's Guide to the Magus

[Kurald Galain]

the Brewkeeper says "A draught functions as a potion or oil"

Ah, that's good. I was worried they had created yet another type of potion-like objects that don't count as potions.

Of course, the brewmaster is disallowed in PFS (because it has Brew Potion as a prereq) so that means they probably won't errata it. Yes, that makes it a very good prestige class, and since Paizo doesn't have a lot of those I welcome the addition. I'd say that it works fine with the Chalice (although the chalice explicitly requires a standard action) and that's a good combo; and that the bountiful bottle gives a potion with the exact same expiration limits as the original (meaning it's effectively a cheaper-but-slower Pearl of Power for the brewmaster).
