I feel like this move is a little too strong.
The amount of damage a player can do in less than one second is enough to wipe the entire party. It's extremely unforgiving.
Consider capping the damage?
Or Making it only count from WS/Burst damage.
Or the First hit while readying dealt to all 6 players undivided.
Or time limit on use.
Or can only use every 5th tp move.
Or lower it's massive regain.
