Ability:Crabalanche

Requirements:You are in a mob of crabs.

You move a distance up to your movement speed. You may do this even if creatures with a size less than the participants in this mob are in the way so long as there is any physical space available for you to pass over them. Any creatures that you pass over in this process make a strength feat save with a DC equal to 3 × N where N is the number of participants in Crabalanche. This is used collectively by all participants of the mob, not once per member.

End condition:At the start of each of the target's turns, they roll 2d4. If either of these dice roll a 4, this effect ends.On fail:Target takes N arm or leg hacks on limbs of their choice and is snared.On success:Target takes N / 2 arm or leg hacks on limbs of their choice.
