Secret bosses
Every world hides one secret boss behind a fake wall or concealed area. Each guarantees an accessory drop on defeat — the drop is always 100%, only the rarity (Common → Secret) varies. That makes secret bosses the most reliable gear farm in the game.

Farming rules that apply to all four
- Accessories always drop. Every kill is a rarity roll — keep farming until the high-rarity version lands.
- Avatar drops are flagged as one-time: the grind is for the accessory rarity roll and the ultra-rare avatar, not duplicates.
- Stack Drop effects — a Drop potion plus the 1.5x Drop mount from Trials or the Release Pass is the intended way to hunt rare boss drops.
- Secret bosses sit above regular enemy HP. Build around your highest-rarity companions before camping them.
Hunter City (World 5, added in Update 1) has its own secret boss whose identity and drops are not yet verified — it is listed as a gap on the about page rather than guessed at.
