Decay

Curse
Unplayable.
At the end of your turn, if this is in your Hand, take 2 damage.

Unplayable. If it is in your hand at the end of your turn you take 2 damage. The code deals it as ordinary damage with no Unblockable flag, so any Block you still have absorbs it, and it is marked Unpowered so no Strength or similar modifier changes the 2. It fires each turn it sits in hand and shuffles back after being discarded.

When to take Decay

Remove it when a shop or event offers, since 2 damage a turn adds up over a run. It is never an emergency if you end turns with a little Block left.
