Slay the Spire · Ironclad Common Attack
Heavy Blade
Heavy Blade deals damage, with Strength affecting its damage multiple times; the listed upgrade increases that multiplier.
How it works
The card list records 14 damage for both versions. Its base text says Strength affects the card 3 times, and the upgraded text says Strength affects it 5 times. Heavy Blade is listed as a Common Ironclad Attack. No other scaling rules or damage comparisons are provided in the passage.
