Void Rend is a legendary major card out of the New mechanic pool. Shadowstep strikes one body only, at 140% damage, executing below 50% health.

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 Reaper and Ghost Step. Take one and the rest are gone for the run.
