Bosses

A giant boss rock waits at the end of every path. Break it before the timer runs out for star shards, a pile of coins and, with some luck, ores.

How boss fights work

  • The boss sits in the Boss Arena at the end of a path. You unlock the arena with coins.
  • The timer starts as soon as you enter the arena. If it runs out, the boss heals to full and the timer restarts.
  • If everyone leaves the arena, the boss heals too, so hit-and-run doesn't work.
  • While you drill the boss, your equipped pets attack it once a second on their own. The "Damage/s" column in the pet tables matters here.
  • Breaking the boss gives ⭐ star shards, a big burst of dust worth coins and 3 rolls for ores.
  • A broken boss respawns after a while.
