Girya
Girya is a rare relic that allows you to gain Strength at Rest Sites, but only up to 3 times total across the entire run. When you visit a campfire, a new option appears alongside heal and smith: you can gain 1 Strength. This option can only be used 3 times before it is permanently exhausted.
Each use of Girya is 1 permanent Strength, which multiplies across every attack for the rest of the run. Using all 3 charges gives 3 permanent Strength — equivalent to what Vajra provides at combat start, but permanently and cumulatively. Girya forces difficult decisions at rest sites: take the Strength, heal, or upgrade a card. It is best used when you're in good health and don't urgently need healing or upgrades. The relic rewards long-term planning and is strongest in attack-heavy builds where Strength amplifies every hit.
