Echoing Slash

SilentAttackRare
Deal 10 damage to ALL enemies.
Repeat this effect for each enemy killed.

One play deals 10 damage to every enemy. The code then counts how many of those hits killed something and queues that many further full sweeps, and each new sweep can add more. Kill two enemies in the first wave and two more waves follow. The loop ends only when a wave kills nothing. Upgraded, each wave deals 13.
