Notes

: Before resorting to , use any high base HP light cone off Path, specifically 1164+/1058+ base HP light cones.
(4): For higher invested Castorice teams.
HP% / Quantum DMG Boost: HP% is preferred for builds with lower number of HP subs and Quantum DMG Boost% for builds with higher number of HP subs. If unsure, default to HP% Planar Sphere.
SPD / CRIT Rate: Assuming is being used, as it requires under 95 SPD to acquire 32% CRIT Rate buff in combat. If not using , aim base SPD and 100% CRIT Rate out of combat, and subtract CRIT Rate buffers (if applicable) accordingly.
HP: With HP% Planar Sphere.
Basic ATK: Basic ATK can be ignored.

Overview

Summary and General Analysis

  • Castorice is a DPS who frequently summons and detonates her Memosprite Netherwing to deal damage.
  • When allies gain or lose HP, Castorice gains "Newbud" charge for her Ultimate. Once she reaches 100% "Newbud", she can use her Ultimate to summon Netherwing. Netherwing uses her Memosprite Skill to consume HP to deal damage up to three times before detonating.
  • Castorice's Skill consumes allies' HP while dealing damage. If Netherwing is on the field, she performs a Joint Attack instead.
  • When Castorice is in a Trailblazer's account, the first time an ally would be downed, they instead delay being downed for 2 turns or until they receive healing or shielding. This effect applies regardless of whether Castorice is on the team or not.
  • Castorice's performance heavily relies on Hyacine to consistently generate "Newbud" and maintain her Ultimate uptime.

Investment Priority

E2 > S1 > E1

  • E2 allows Netherwing to use her Memosprite Skill 2 additional times, causes Castorice to immediately take action after using her Ultimate, and grants additional "Newbud". The extra "Newbud" generation combined with the additional attacks allows Castorice to cycle through her Ultimate more frequently while significantly increasing her damage output.
  • S1 increases her damage output and provides Action Advance after Netherwing detonates. Is a strong Light Cone option, particularly due to the limited number of Remembrance Light Cones available.
  • E1 increases Netherwing’s damage against enemies below certain HP thresholds.
