Strengths & Weaknesses

Bronya

Strengths
  • Ultimate “The Belobog March” buffs allies’ damage for a short window—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • “Combat Redeployment” action-advances an ally with a damage amp attached—one Skill Point buys a full extra carry turn.
  • Talent “Leading the Way” After using her Basic ATK, Bronya's next action will be Advanced Forward by 38%—ignore it and Bronya plays like a worse generic Harmony unit.
Weaknesses
  • Buff windows on “The Belobog March” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Bronya’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 “Combat Redeployment” every turn without watching Skill Points strands the rest of the team—Bronya is often the SP sink.

Ruan Mei

Strengths
  • Ultimate “Petals to Stream, Repose in Dream” Ruan Mei deploys a Zone that lasts for 2 turns—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • Skill “String Sings Slow Swirls” After using her Skill, Ruan Mei gains Overtone, lasting for 3 turn(s)—this is the spend that keeps the rotation honest.
  • Talent “Somatotypical Helix” Increases SPD by 11.0% for all teammates (i.e., excluding this unit)—ignore it and Ruan Mei plays like a worse generic Harmony unit.
