Strengths & Weaknesses

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.
Weaknesses
  • Buff windows on “Petals to Stream, Repose in Dream” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Ruan Mei’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 “String Sings Slow Swirls” every turn without watching Skill Points strands the rest of the team—Ruan Mei is often the SP sink.

Tribbie

Strengths
  • Ultimate “Guess Who Lives Here” hits every enemy on the field in one cast—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • Talent “Busy as Tribbie” fires Follow-Up ATKs off ally Basics—damage keeps flowing even when Tribbie is not the active turn.
  • Skill “Where'd the Gifts Go” Gains "Numinosity," lasting for 3 turn(s)—this is the spend that keeps the rotation honest.
Weaknesses
  • Buff windows on “Guess Who Lives Here” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Follow-Ups from “Busy as Tribbie” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Tribbie’s off-turn damage.
  • Tribbie’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.
