What is Black Star?
Elite enemies award an extra relic.
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
Useful if you can fight multiple elites with safe routing.
What to avoid
Do not take it expecting value without any elite fights.
