Lucia
Lucia is a transformative Support unit whose ability to scale off Max HP while providing massive damage buffs and team sustainability makes her essential for top-tier Ether compositions. Her unique Dream state mechanics allow for consistent uptime on critical combat buffs, ensuring your team remains dominant in extended encounters.
Lucia utilizes a unique resource management system called Dream Points to enter the 'Dream state' and activate the Ether Veil, which grants widespread team buffs. Within this state, she upgrades her attacks into 'Harmony' versions, providing continuous damage amplification and the 'Darkbreaker' status to her squad. Her kit heavily emphasizes Max HP scaling, allowing her to provide utility as a sustain-oriented Support without sacrificing offensive power.

The equipper's Energy Regen increases by 0.4/0.46/0.52/0.58/0.64/s. When the equipper activates Ether Veil or extends its duration, all squad members gain 25/28.8/32.5/36.3/40% increased DMG and 15/17.3/19.5/21.8/24% increased Max HP for 45s. Repeated triggers reset the duration. Only one instance of this effect can exist in the same squad.
Why it works —Perfectly aligns with her HP-based support scaling and provides essential Energy regeneration for consistent rotations.
Energy Regen
While off-field, Energy Regen increases by 0.6/0.75/0.9/1.05/1.2 per second. Attacks from the equipper enhance the squad's DMG against a struck target by 10/12.5/15/17.5/20% for 3 seconds. During this period, this effect is further increased by 1.7/2/2.5/3/3.3% every 0.5s, up to a maximum additional increase of 10.2/12/15/18/19.8%. Repeated triggers only refresh its duration without refreshing the DMG increase effect. Passive effects of the same name do not stack.
Why it works —A strong alternative focusing on Energy efficiency, ensuring she can frequently trigger Harmony abilities.

Energy Regen
When any friendly unit in the squad attacks and hits an enemy, all friendly units' ATK increases by 2.5/2.8/3.2/3.6/4% for 8s, stacking up to 4 times. The duration of each stack is calculated separately, and each friendly unit can provide 1 stack of the buff. Passive effects of the same name do not stack.
Why it works —The accessible F2P option, providing solid stat boosts if specialized support engines are unavailable.
CRIT Rate
Whenever the equipper's attack triggers an Attribute Counter effect, all squad members' CRIT Rate against the struck enemy increases by 12/13.5/15.5/17.5/20% for 12s. The bonuses triggered by the same type of passive effects do not stack.

When Lucia's initial Max HP reaches 24,000, the above bonus effect reaches its maximum value. When any Harmony deals DMG, Lucia increases the final attack's DMG by an additional % of her Max HP.
