Sun | Assassin | Single-target Debuff DPS | Impact
Burn and Recovery Down are both attached to her damage buttons, so she benefits from a mixed crit-plus-hit stat line. From there, branch into the Damage route and the Tempo route as your gear options widen.
Marcille feels best once Speed, Crit Rate, and Crit DMG are online, giving the first rotation a much steadier payoff.
Skill investment is cleanest as Ultimate >= Special >= Basic, with the first cooldown setting the pace for the full rotation.
Lead with the highest-invested cooldown so the opener starts on the strongest possible breakpoint.
Special is usually the next meaningful breakpoint once the opener lands and should carry the mid-cycle payoff.
Use Basic between cooldowns while you keep Speed and Crit Rate stable on gear.
Budget target is 3 / 3 / 3, with 7 / 8 / 8 as the long-term skill finish.
Start on the Core line with Insight (4pc) + Hit (2pc) and Speed necklace and ATK% ring. Move into the Damage route and the Tempo route once the baseline is stable.

Passive
Marcille's passive matters more once the core stat line is online and the rotation is already stable.
Basic
Use the basic to bridge cooldowns; it should stay behind the two higher-impact skills in upgrade priority.
Special
Special is the next major breakpoint after the opener and usually carries the mid-cycle payoff.
Ultimate
Ultimate anchors the opener and stays at the top of the investment order for this build.
