Vajra

Vajra is a Common relic in Slay the Spire 2 that provides 1 Strength at the start of every combat. Strength increases the damage dealt by all Attack cards, meaning every Strike, heavy hitter, and multi-hit Attack in your deck benefits from this passive bonus for the entire fight.

This is one of the most universally useful Common relics in the game. A single point of Strength may seem modest, but it applies to every Attack card you play, and on multi-hit cards like Pummel or Sword Boomerang, the bonus multiplies with each hit. Aggressive builds that play many Attacks per turn will see the largest cumulative damage increase over the course of a fight.

Vajra synergizes naturally with other Strength-granting effects like Inflame, Demon Form, and Limit Break, accelerating Strength-scaling strategies. It also pairs well with Pen Nib and other damage multipliers. There are virtually no downsides to picking up Vajra, making it a reliable early pickup that stays relevant throughout an entire run.
