World Bosses
The world boss is STARLESS's weekly set-piece: a rotating boss you get a limited number of attempts at, scored by grade rather than by beating anybody. There is no PvP in STARLESS. Nothing another player does can lower your score, take your reward, or put you behind — you are measured against the boss and its published counters, full stop.

How to actually score. Every boss publishes its counters. Ignoring a phase
requirement does not lock you out — it caps your damage at the multiplier shown, so a
broad roster out-scores a single over-levelled unit. Breadth is the skill expression here, which is
also why nothing in the roster is purchase-exclusive.
