Strengths & Weaknesses

Mydei

Strengths
  • Ultimate “Throne of Bones” Blast-hits the main target plus adjacent enemies—most of the kit’s damage lives inside that window, not on filler Basics.
  • Skill “Deaths are Legion, Regrets are None” spends HP as a deliberate self-damage cost—the rotation wants controlled self-damage, not panic healing that cancels the state.
  • “Blood for Blood” spends HP as a deliberate self-damage cost—cleaving a trash mob can snowball into another full Skill/Ult cycle.
Weaknesses
  • E0 without “A Thankless Coronation” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Destruction carries—plan the cone before deep eidolon hunting.
  • HP-spend skills mean Mydei can soft-lock if sustain is weak or if a healer tops them up at the wrong time and breaks a low-HP / Charge condition.
  • Extra-turn and single-target Ultimate patterns shine on bosses but stall in Pure Fiction unless adds die fast enough to proc the talent loop.

Yunli

Strengths
  • Ultimate “Earthbind, Etherbreak” hits every enemy on the field in one cast—level this before polishing filler traces.
  • “Bladeborne Quake” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
  • Talent “Flashforge” Blast-hits the main target plus adjacent enemies—good play literally shortens Ult cooldown.
Weaknesses
  • E0 without “Dance at Sunset” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Destruction carries—plan the cone before deep eidolon hunting.
  • If Energy or Skill Points starve “Earthbind, Etherbreak”, Yunli spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
  • Spamming “Bladeborne Quake” every turn without watching Skill Points strands the rest of the team—Yunli is often the SP sink.

Pela applies DEF shred / vulnerability so the carry’s multipliers actually land.

With Mydei

Gallagher covers HP / memosprite upkeep so the Remembrance loop does not collapse mid-wave.

With Yunli

Gallagher covers healing (and often Energy / cleanse) so the carry can stay on-curve.
