That is, if you have an AoE knockback effect (like Turn Demon), make it knock away from the center of the effect rather than homogeneously away from the player.
I've suggested multiple times before a way to control the direction of knockback and I wholeheartedly agree that spells like such should implement it. Turn Demon though would make more sense just pushing away because of the spell, but it would make psycho shove for instance more unique and have more utility while making stunlocks with it harder.
