Bladestorm is a legendary major card out of the New mechanic pool. Whirlwind reaches 8 u and hits 16 targets per spin at 70% damage; cooldown 15% longer.

You can take it once · it only turns up when your Special ability can actually use it · it can be offered for 0 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Cyclone and Juggernaut. Take one and the rest are gone for the run.
