Ultimate Guide to Reverse 1999 Lucy Build: Skills, Top Psychubes, Insight Materials, and Team Compositions

Lucy is a 6-star character in Reverse 1999, available for players to summon from the anniversary-limited banner, Thoughts in Cylinder. As a DPS unit, Lucy possesses the ability to enhance her incantation skills during combat. Additionally, her skill set allows her to execute a follow-up attack when she reaches Insight III.

Though she is classified as an Intelligence-type character, Lucy benefits from the Pragmatist effect, providing her with a compelling advantage against enemies of all Afflatus types. This advantage is activated through her Ultimate Skill, A Step Forward.

This article outlines the best Psychubes, Insight Materials, team compositions, and a detailed explanation of Lucy’s skills for players eager to incorporate her into their strategy.

Reverse 1999 Lucy Build Guide: Skills

Below are the skills of Lucy in Reverse 1999:

Power of Speed (Basic Skill 1): Lucy inflicts 200%/300%/500% Reality damage on a single enemy using one/two/three-star rank cards. After upgrades, Power of Speed targets two enemies—the primary target receiving 220%/330%/550% and the secondary 110%/165%/275% Reality damage. For an upgraded Power of Speed, Lucy can consume five stacks of Dynamo to deal an extra 60%/90%/150% Reality damage.
Electric Surge (Basic Skill 2): Lucy deals 150%/225%/375% Reality damage to all enemies when using one/two/three-star rank cards. If there are three or more enemies, she can consume 10 stacks of Dynamo to hit an additional target. If there are fewer than three enemies, she inflicts an extra 40%/60%/100% Reality damage. When upgraded, Electric Surge deals reality damage enhanced by her Genesis damage based on her attack.
A Step Forward (Ultimate Skill): Lucy gains the Pragmatist status for two turns, acquires one stack of Data Iteration, and loads two Charged Ammunition. After upgrading, she benefits from enhanced effects including two stacks of Overcharged Ammunition and gains a Moxie.

Explanation of Lucy’s Status Effects

Pragmatist: Grants Lucy an advantage over any Afflatus, providing a 10% damage bonus that cannot be dispelled.
Data Iteration: Enhances her attack by 4%, stacking up to five times without being dispelled.
Charged Ammunition: Provides 10 stacks of Dynamo, which decrease by one stack after each trigger.
Overcharged Ammunition: Similar to Charged Ammunition, supplying 10 stacks of Dynamo while reducing one after each trigger.

It’s important to note that Lucy can upgrade one of her three incantations at the start of each round. If she upgrades all three incantations, including her follow-up attack Conservation of Energy, she will upgrade her Ultimate Skill. The follow-up attack can be executed at Insight III.

Players can utilize Lucy as a DPS character in their Reverse 1999 teams. She synergizes well with Arcanists capable of dealing Reality damage and gaining either Moxie or Eureka. Moreover, her ability to gain an Afflatus advantage makes her a strong addition to a variety of teams.
