Displacement

When hit with bludgeoning, piercing, slashing, or force damage, react by curling into a ball and instead of taking damage get knocked back a number of feet equal to the damage times 2 and if that number is more than 10 you are also knocked prone. You take none of the previously mentioned damage types until the start of your next turn, but you still take other damage types, even if they were part of the attack that provoked the reaction.
