Castorice 
Remembrance Aidonia, the snowy land that respects and worships death, has already sunken into sweet slumber. O Castorice, daughter of the River of Souls, the Chrysos Heir in search of the Coreflame of "Death," set forth! Guard the lament of the souls in this world, and embrace the solitude of destiny. — Life and death is a journey. When a butterfly rests on that dead branch, the withered will be reborn again.

Castorice Best Teams
Castorice • Trailblazer (Ice) • Pela • Lynx
A F2P-friendly Castorice setup anchored by the Remembrance Trailblazer for turn-advance, True DMG and CRIT DMG buffs. Pela lowers enemy DEF to amplify damage while Lynx raises Castorice's Max HP to support her HP-consume mechanics.
Castorice • Evernight • Cyrene • Hyacine
An all-around high-damage Castorice team: Evernight + Cyrene provide the most consistent offensive buffs for Castorice, while Hyacine offers team healing and Max HP increases to accelerate Castorice's Newbud charging and survivability.
Castorice • Mydei • Tribbie • Gallagher
A dual-DPS HP-consume composition where a second HP-consuming DPS (Mydei, Blade, Jingliu, Arlan) helps charge Castorice's Ultimate. Tribbie offers buffs/high HP while Gallagher supplies sustain through Besotted interactions and burst heals.

The maximum limit of "Newbud" is related to the levels of all characters on the battlefield. For every 1 point of HP lost by all allies, Castorice gains 1 point of "Newbud." When "Newbud" reaches its maximum limit, can activate the Ultimate. When allies lose HP, Castorice's and Netherwing's DMG dealt increases by 0.1%. This effect can stack up to 3 time(s), lasting for 3 turn(s). When Netherwing is on the field, "Newbud" cannot be gained through Talent, and every 1 point of HP lost by all allies (except Netherwing) will be converted to an equal amount of HP for Netherwing.
