What is Cracked Core?
Defect starting relic placing a Lightning orb at combat start.
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
Plan the free orb slot and early channel order.
What to avoid
Do not accidentally Evoke the starting Lightning instead of desired Frost.
