How players use it
- Run plan by year Councils in years 13, 21 and 29. Overwork makes support buildings apply their effect again (up to 3 times). 3DM’s decree list ranks it first, and Vao calls it important for fast scaling. Feast doubles troop HP for tank carries. Venom doubles poison for Cauldron and Poison Vial builds. Gunpowder widens area attacks for base carries. Take Rebirth, which gives 3 lives beyond your maximum, when you are down to one life.
How to get it
- In the King of Nature's 9-card deck: a run as this king can start with it, and losing a battle offers cards from your own deck.
- Loot after beating the King of Nature in battle when that king is one of your enemies.
- Merchant: Jack of Magic (tomes and enchantments).
- Joker mode: pick it for a custom deck.
