When to Pick Corruption
Corruption is a 3-cost power card for the Ironclad. Powers offer lasting value across the entire fight. Pick this when your deck needs scaling.
When to Skip
At 3-cost, this is on the higher end of the cost curve. Without reliable energy generation, it may sit dead in your hand. Powers require a setup turn. If your deck lacks defense or needs to act immediately, skip until you have the energy to spare. This card provides no direct damage, block, or draw. It is a situational pick — prioritize basic needs first.
Upgrade Value
High upgrade priority. Cost becomes 2 — these changes significantly improve the card's efficiency.

Is Corruption worth taking?
S-Tier · Exhaust engineCorruption is one of the strongest Ironclad powers. It makes every Skill cost 0 and exhausts it, which turns a normal defensive turn into a chain of free block, draw and exhaust payoffs. The catch is that you only get each Skill once.

How to play Corruption
- Play it as early as you can afford the 3 energy. Every turn you delay is a turn of free Skills you never get back.
- Treat your Skills as a one-time resource. Spend the cheap ones first, save the high-impact ones for the turn they matter, and let exhaust payoffs turn the losses into draw or block.
- Upgrade it when the deck is ready. Dropping it to 2 energy makes the setup turn much less painful, especially before an elite or boss.
Common mistakes
- Playing it in a deck with very few Skills. Corruption needs a steady stream of Skills to convert the free cost into value.
- Forgetting that the Skills exhaust. If a Skill is your only answer to a later turn, spending it early can leave you without an answer.
Cards that work with Corruption
Corruption is an exhaust engine first and a cost reducer second. Dark Embrace and Feel No Pain turn each exhausted Skill into cards or block, which is why the package is so strong.
Where to get Corruption
Corruption is an Ancient-rarity card, outside the normal common/uncommon/rare reward curve. It shows up through Ancient encounters and special rewards, so treat it as a lucky find rather than something you can force every run.
