Lilya — Review & Analysis

Lilya
Lilya is a Star-Afflatus single-target DPS built entirely around Crit: her Ultimate A Little Trick is a 700% Reality DMG finisher, while Crosswind Takeoff chains a bonus attack that counts as its own action whenever it crits. Her whole passive suite feeds Crit Rate (+10% on entry, +20% on Ultimate, doubled Crit from the Psychube's base stats) and pairs it with Crit-gated lifesteal, making her a self-sustaining single-target assassin whose damage snowballs the more Crit she stacks.
Strengths
  • A 700% Reality DMG single-target Ultimate that hits hard as a boss finisher.
  • Layered passive Crit Rate (on entry, on Ultimate, doubled Psychube Crit) lets her reach Crit thresholds without leaning on a dedicated buffer.
  • Critting with Crosswind Takeoff triggers a bonus attack counted as its own action, and her Ultimate lifesteals on Crit, giving her burst plus built-in self-healing.
Weaknesses
  • As a Star Afflatus she's restrained by Plant, taking a clear damage cut against Plant enemies.
  • Her kit leans heavily on Crit: the follow-up, the lifesteal and her consistency all require high Crit Rate, so she performs erratically until enough Crit is stacked.
Build Priority

Level her Ultimate A Little Trick first to maximize the finisher and her Crit threshold, then Crosswind Takeoff so the Crit follow-up hits harder. Since her passive doubles the Crit effect from a Psychube's base stats, favor a Psychube leaning into Crit Rate and Crit DMG, backed by ATK, to push her single-target damage ceiling.
