Molten Fist

IroncladAttackCommon
Deal 10 damage.
Double the enemy's Vulnerable.
Exhaust.

Ten damage (14 upgraded), then, if the enemy is still alive and has Vulnerable, it gains that much Vulnerable again, doubling the stack. The hit comes first, so the doubled Vulnerable boosts your later Attacks, not this one, and an enemy with no Vulnerable gets nothing extra. The card Exhausts.

When to take Molten Fist

Take it in an Ironclad deck with two or more Vulnerable sources, since it doubles whatever Vulnerable an enemy carries. Otherwise it is a weak exhausting attack, so skip it.
