Scripted mechanic Do the announced job immediately: run to the centre for Headmaster's Office, and read each title the same way. Finish the movement before going back to damage.
Form change Treat the threshold as a reset: stop your rotation, re-read the boss's new telegraphs, and reposition before committing damage again. Inferred from game data — not yet verified in game
Form rhythm Learn the order of the forms and pre-position before each swap. Do not wait for a cast bar; the data records no telegraph. Inferred from game data — not yet verified in game
Break armor At the 60% threshold, run over one rune before returning to damage. Either rune works, so take the closer one and do not cross the boss to reach the other. Inferred from game data — not yet verified in game
Room sequence Cross to the dividing line when the call comes and stand in the half that is not burning; cross only after the active half finishes. Do not cross through the burning half.
