Overview
Sunday is a 5★ Imaginary Harmony from Penacony, playing Support in most teams. Imaginary Harmony buffer who enables memokeeper teams with CRIT and action advance.
How to Play
Sunday is a tempo piece — cast buffs before your carry moves, then stay ready to refresh them every few turns. Speed boots help you act twice before the DPS window closes. Cast buffs before your carry acts — Speed tuning matters more than personal damage.
Team Rotation
Turn 1: Sunday Skill buff → immediate swap to carry → Basic Attack or Skill with carry → Sunday Ultimate before buffs fall off. Reapply buffs every 2–3 turns.
Strengths
Sunday excels in Imaginary Harmony teams from Penacony. Strong team amplification that multiplies your carry's output. Signature Light Cone and endgame relics unlock their full ceiling.
Weaknesses
Sunday contributes little personal damage. If buffs expire early due to Speed mismatch, team DPS collapses.
Investment Priority
E0 Sunday clears story and Simulated Universe. For Memory of Chaos, level talents to at least 6/8/8, farm recommended relics from their build page, and hit Speed breakpoints with SPD boots. Pull or craft a matching-path 5★ cone if they are a long-term main; otherwise use the best F2P path option at S5.
