RegentAttackCommon
Deal 11 damage.
Add a Debris into your Hand.
  • Cost 0 Energy: it deals 11 damage, 15 upgraded, to one enemy, then puts a Debris into your Hand.
  • Debris: a Status that costs 1, does nothing and Exhausts when played.
  • Unplayed: it goes to the Discard Pile at end of turn and returns with every shuffle, so each cast adds a dead card to the combat unless you spend 1 Energy to clear it.
  • Counts as created: the Debris counts as a created card.

When to take Collision Course

Eleven free damage is excellent tempo for Act 1 elites and a strong opener in short fights. In long boss fights the Debris tax adds up, so value it lower there.
