Oddly Smooth Stone

Oddly Smooth Stone is a Common relic in Slay the Spire 2 that grants 1 Dexterity at the start of each combat. Dexterity increases the Block gained from all card sources, making every Defend, Backflip, and defensive Skill in your deck more effective for the entire fight.

This relic is the defensive counterpart to Vajra and is universally strong across all characters and builds. Even aggressive decks benefit from the added survivability, as the extra Block per card compounds significantly over a long fight. Characters like the Silent, who frequently play multiple Block-generating Skills per turn, extract especially high value from this relic.

Oddly Smooth Stone pairs beautifully with cards and relics that scale off Dexterity or generate Block multiple times per turn. It becomes even more potent alongside other sources of Dexterity like Footwork, creating a stacking effect that can make your defensive cards absurdly efficient. There are no real anti-synergies to worry about, making this one of the most reliable Common relics you can find.
