Bash
Bash deals damage and applies Vulnerable. Its listed upgrade increases both the damage and Vulnerable applied.
Understand this choiceThis reference focuses on ten Ironclad cards listed for Slay the Spire 1: Bash, Clash, Flex, Headbutt, Heavy Blade, Perfected Strike, Shrug It Off, True Grit, Spot Weakness, and Corruption. Their recorded text describes attacks, Block, Strength changes, card retrieval, and Exhaust-related effects. Where the source gives both base and upgraded text, both are included so the listed change is clear. The card list supplies functional descriptions but does not establish comparative effectiveness, acquisition locations, costs, or a recommended deck. Ascension and other progression systems are outside this focused card reference.
