Burn

Burn is a status card added to your deck by certain enemies (most notably the Automaton boss). It is Unplayable and deals 2 damage to you at the end of each turn it remains in your hand. Upgraded Burn deals 4 damage per turn instead, making encounters that inflict multiple Burn cards increasingly punishing. Unlike most statuses, Burn can be upgraded by a Smith, which is generally something you want to avoid. Burn stacks are best managed by cycling through your deck quickly to exhaust them or by using cards that exhaust cards in your hand.
