Bash
Bash deals damage and applies Vulnerable. Its listed upgrade increases both the damage and Vulnerable applied.
How it works
The card list gives base text of 8 damage and 2 Vulnerable. Its upgraded text gives 10 damage and 3 Vulnerable. The source labels Bash as a Basic Ironclad Attack. It does not describe acquisition or play cost in the retrieved passage.

This does not attempt a complete card, relic, character-unlock, or Ascension guide. Guidance explains the referenced mechanics; it is not a tested damage ranking.
