Hows about pilling on or some new skill works like tentacles but holds the player on the ground.
I.e. you pile onto a player to keep them pinned to the ground. When they try to take an action to stand up they make a tentacles like roll to try and get away from you.
Guess you could call it Pin or something like that.
Would perhaps reduce the bash on the elves but allow the bash to temporarily subdue key players.
Anyways, half baked idea so feel free to flay it to bits
