Achievement map

Three places where winning the stage is only part of the job: a chessboard to use, egg nests to burn, and a Yeti that needs to eat enemies.

Arcane Academy: Checkmate!

The chessboard sits at the lower-left edge of the battlefield. It is a map interaction, not an enemy to kill.

  1. 1 Chessboard

The chess sequence

  1. Use the white knight to take the rook on the right.
  2. Use the white bishop to take the rook on the left.
  3. Use the white rook to take the bishop.

Checkmate! asks you to win the board interaction. Welcome to the Masterclass is a different badge: finish the stage without activating the statues' teleport. If enemies trigger that rescue, restart for that objective.

Abominable Lair: let the Yeti eat

All You Can Eat Buffet requires the boss to eat 30 enemies. Defeating him awards Not Dead Yeti, but does not complete the eating requirement for you.

Separate the achievement attempt from the boss kill

  1. Wait for the doorway's ice to melt.
  2. Ring the bell when enemies are grouped in front of the doorway, so the boss eats them.
  3. Continue until the achievement unlocks, then finish the fight. Keep your heroes clear of his eating range.

Imperial Gunner is another interaction on this stage: kill five enemies with one imperial walker shot. It fires only once per run, so wait for a group in its firing area rather than activating it on the first enemy.

Ice-hole map and the J.T. fight

Frostbite Nest: Protein-Rich

Destroy ten egg nests. The nest's Flaming Arrow Volley costs 50 gold per activation, so ten activations need a 500-gold budget alongside your defense. Trigger the volley while there is an egg to destroy, before it hatches.

Keep the defense running while you collect

  • Keep gold in reserve instead of buying every optional upgrade.
  • Clear towers webbed by Sarelgaz before working on the next nest.
  • Confirm Protein-Rich in the game before marking it complete; beating Sarelgaz is the separate Forced Molting badge.

Keep track of what actually unlocked

Use the 53-achievement checklist to mark your unlocked badges. For mode and difficulty wins, use the separate completion tracker. Both keep your marks in this browser and offer a backup export.
