Searing Blow

Searing Blow is an Attack card for the Ironclad. It deals 12(+) damage. As an Uncommon card, it appears as a reward for combat, although less often than Commons.
This card is unique because it can be any number of times. Each upgrade causes the card to deal sequentially more damage. There's no limit to how many times this damage bonus can apply.
The damage increase from an upgrade increases each time:
