Keep the Heroes Out!: Boss Battles

At the end of Wave 1, follow the scenario’s instructions before reshuffling the Guild deck; resolve any Instant abilities immediately and complete any changes to the deck in the order given. The scenario explains how to prepare Wave 2 and when to introduce the Boss (p. 6).

No. After resolving a Boss card, put it on the bottom of the Boss deck; the Boss deck does not run out (p. 6).

Not necessarily: in Boss Battles, you must defeat the Boss to win, while also protecting Treasure 4 in the Vault. If the Guild deck runs out while the Boss is still active, you lose; losing Treasure 4 can also cost you the game (p. 6).

Place one heart token on the Battle board for each damage dealt. Whenever you have five heart tokens, exchange them for one token on the “heart 5” slot; reaching the scenario’s required damage ends the game immediately (p. 6).

Follow the timing in that scenario: Boss Battles generally have you reactivate the Boss after each Heroes phase, resolve its Boss card, and then resolve the Boss and active Heroes, but the exact sequence is scenario-specific (pp. 12, 14, 16, 20, 22, 24, 26, 29, 31–32).
