The best Sunday build in HSR turns this 5-star Imaginary Harmony character into the team’s action-advance and CRIT DMG engine. His Skill sends an ally, and their summon, forward immediately with a DMG buff, while his Ultimate refunds energy and stacks even more CRIT DMG onto that same target.
I’ve put together the Light Cones, Relics, trace priority, stat priority, teams, and Eidolon verdicts for the best Sunday build so you can get the most value out of him whether you’re pairing him with a Summon-based carry or a standard hypercarry.

How to Play Sunday: Rotation and Tips
Sunday’s loop is simple to run but rewarding to optimize: use his Skill, Benison of Paper and Rites, on your main damage dealer so they act immediately and deal 15% to 40% more DMG depending on whether they have a summon out. Once that ally has been hit by his Ultimate, Ode to Caress and Cicatrix, they become “The Beatified” for 3 turns, gaining bonus CRIT DMG scaled off Sunday’s own CRIT DMG stat.
Open every fight with his Technique, The Glorious Mysteries, since it adds another 50% DMG buff to the first ally he targets in the next battle. From there, alternate Skill and Ultimate on the same carry to keep The Beatified refreshed and your damage dealer swinging for as much as possible each turn.
