I like the vortex maw well enough, though we may have to work on convincing Cleon.
So you don't like gulp or charging bite? This thing should be very efficient at swallowing, not be tied up with a single opponent.
Something like engulf could work. Care to write that up?
That would work. I might also consider making it a move or even swift action.
Well, if Shade likes, I'm ok with reopening the elemasters.
Back to the draeden: making the maw an alternate attack is fine with me. Or a move action, either way.
