Recently I've been looking at the Skald and found the War Drummer archetype, which I absolutely love for being a "smashy smash" approach to the class, and eventually, I started thinking about the Hunting Horn from Monster Hunter, which would be perfect for this class/archetype.

However, I think it would work even better if there was a much smaller focus on casting. Is there a better way to emulate a Hunting Horn Monster Hunter without spellcasting that's PFS legal (I found Fighter/Barb with Bard VMC, but VMC is illegal without a special boon)?
