Strengths & Weaknesses

Sunday

Strengths
  • Ultimate “Ode to Caress and Cicatrix” refunds a meaningful chunk of Energy inside the Skill—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • “Benison of Paper and Rites” action-advances an ally with a damage amp attached—one Skill Point buys a full extra carry turn.
  • Sunday’s memosprite/summon adds a second actor that hits and breaks without always spending the team’s Skill Points.
Weaknesses
  • Buff windows on “Ode to Caress and Cicatrix” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Sunday’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
  • Spamming “Benison of Paper and Rites” every turn without watching Skill Points strands the rest of the team—Sunday is often the SP sink.

Yukong

Strengths
  • Ultimate “Diving Kestrel” buffs allies’ damage for a short window—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • Skill “Emboldening Salvo” Obtains 2 stack(s) of "Roaring Bowstrings" (to a maximum of 2 stacks)—this is the spend that keeps the rotation honest.
  • Talent “Seven Layers, One Arrow” Basic ATK additionally deals Imaginary DMG equal to 100% of Yukong's ATK—ignore it and Yukong plays like a worse generic Harmony unit.
Weaknesses
  • Buff windows on “Diving Kestrel” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Yukong’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
  • As a 4★ Harmony unit, Yukong is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
