What is Whirlwind?
Spends available energy to hit all enemies repeatedly, rewarding extra energy and Strength.
This reference covers gameplay decisions in the original Slay the Spire. Character-specific options and relic synergy can change how useful an item is, so consider your current deck, health, upcoming enemy and available resources before applying a strategy.
When and how to use it
Particularly useful against grouped enemies and when resources are saved for a burst turn.
What to avoid
Zero planning for energy and defensive needs can make a large Whirlwind turn unsafe.
