Lesson Learned will upgrade a random card in your deck if it is used to kill an enemy. After being used it exhausts, whether it has killed an enemy or not.

The kills must be considered Fatal to upgrade a card. Not all enemies count as Fatal kills (exceptions detailed below).

Interactions[edit | edit source]

  • Lesson Learned is capable of upgrading itself.
  • Exhume can be used to return Lesson Learned to your deck, allowing for more than one use or kill per battle.
  • StrangeSpoon.png Strange Spoon gives a 50% chance that Lesson Learned will not exhaust on use.
  • Minions do not count as Fatal kills. These are recognized by the Icon Minion.png icon. For a list of minion enemies, see the Minion page.
  • If fighting Darklings, reducing the HP of one of them to 0 does not count as a Fatal kill unless it was the final enemy from the batch.
  • Defeating the first phase of the Awakened One does not count as a Fatal kill.
