What is Transient?
Act III monster that disappears after a limited time, with huge attacks that weaken when damaged.
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
Deal enough damage each turn to reduce its attack rather than blindly blocking.
What to avoid
Trying to defeat it conventionally without a massive combo is usually wasteful.
