Eagle — Review & Analysis

Eagle

Eagle is a crit-based single-target Reality DPS. Her Ultimate hits for 400% with +40% Crit Rate and converts overflow Crit Rate into Crit DMG, while her passive self-applies -20% Reality DEF and Crit DEF on the strongest enemy and grants herself bonus Crit DMG. Incantation I rewards striking targets under [Debuff][Status Ailment][Control] with extra damage and lifesteal, so she shines most in control/debuff teams.

Strengths
  • 400% single-target Ultimate with +40% Crit Rate and overflow converted to Crit DMG — huge burst when built around crit.
  • Passive self-supplies -20% Reality DEF and -20% Crit DEF on the strongest enemy plus +15% Crit DMG, so she leans little on outside buffs.
  • Incantation I adds damage and lifesteal against debuffed/controlled targets, while Incantation II grants +30% penetration to chew through high-DEF foes.
Weaknesses
  • Her Plant afflatus is countered by Beast (taking +30% DMG), and her low tier placement means stronger Reality DPS options exist.
  • Her damage identity hinges on the target being debuffed/controlled — without a partner applying [Debuff][Status Ailment][Control], Incantation I's bonus damage and lifesteal go to waste.
Build Priority

Level her Ultimate first — it is her main burst and carries the crit-conversion mechanic — then Incantation I as her core single-target hit. Since the Ultimate turns overflow Crit Rate into Crit DMG, favor crit-oriented Psychubes (Crit Rate/Crit DMG or ATK): stack enough Crit Rate, then pile on Crit DMG to maximize output. Pair her with control/debuff units to trigger Incantation I's bonuses.
