At a Glance
Strengths & Weaknesses
Robin
- Ultimate “Vox Harmonique, Opus Cosmique” action-advances the whole team and opens a concerted damage window—time it for the carry’s damage window instead of casting on cooldown out of habit.
- Skill “Pinion's Aria” buffs allies’ damage for a short window—this is the spend that keeps the rotation honest.
- Talent “Tonal Resonance” refunds a meaningful chunk of Energy inside the Skill—good play literally shortens Ult cooldown.
- Buff windows on “Vox Harmonique, Opus Cosmique” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
- Robin’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 “Pinion's Aria” every turn without watching Skill Points strands the rest of the team—Robin is often the SP sink.
Sunday
- 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.
- 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.
