César

Caesar's signature and by far her best option. 18% Impact, 30% unconditional shield boost, and 18% squad DMG + 12% Daze on any Interrupt or Perfect Dodge — takes her supportive and Daze capabilities to the next level.

Massive HP% and Combat HP% unconditionally plus a Combat Impact boost on hit. Combat Impact doesn't scale her Aegis Shield though — loses to Stun-class W-Engines unless the HP boost is specifically required.

Energy Regen specialist. After taking damage, grants 16% Energy Regen for 12s — transfers to an ally on switch. Easy to trigger given Caesar's Defensive Assist spam. Pick it if Energy Regen is the priority; otherwise Impact-focused options win.

Anomaly-themed niche option. Boosts Anomaly Buildup for Disorder-oriented teams at the cost of Daze and Shield potency — a trade-off that usually doesn't pay off.
