FINALLY beat Slay the Spire with the Ironclad. By 1 HP. Skin of my frikkin' teeth.
Strategy: Lots of defense and attacks that give wounds, get card draw for wounds, use them.
Then also build up strength behind my shield and then POUND THEM TO DUST.
Last attack against the shapes boss was a whirlwind attack that did, like, 24x6 points of damage :V
