Fluid Aura knocks back and stuns for a few seconds. If I hit mob with stone 1, it takes mob out of stun, but doesn't apply heavy. This has never made sense to me. The best use of FA, imo, is for low levels to knock danger out of the way, and then slow them down from getting in your face again. As is, any attack makes the mob get right in your face again, pretty much negates the whole knockback.
All other theories about right and wrong uses for FA aside, this is just a mechanic that makes no sense to me, and has always seemed like an oversight.
