Just out of curiosity as i never tried it when i had a monk splash on my druid.
It mentions that flame blade is not a physical weapon and also that it does not un center monks. Anyone tried to see if you can use stunning fist while they are quipped. (i know normal weapons prevent the use of stunning fist but the not physical weapon part made me wonder)
Edit: Second question is flame blade effected by imp crit slashing in human form (I know its not bludgeon as tested) Scimitars ofc would normally be slashing but the spell description states that it doesn't do slashing damage. (does fire)
