Strengths & Weaknesses

Gilgamesh

Strengths
  • Ultimate “Enuma Elish” hits every enemy on the field in one cast—level this before polishing filler traces.
  • “Gate of Babylon” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
  • Talent “"Amuse Me to the Fullest"” When a teammate uses their Ultimate—damage keeps flowing even when Gilgamesh is not the active turn.
Weaknesses
  • Follow-Ups from “"Amuse Me to the Fullest"” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Gilgamesh’s off-turn damage.
  • E0 without “I Am As You Behold” 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.
  • Spamming “Gate of Babylon” every turn without watching Skill Points strands the rest of the team—Gilgamesh is often the SP sink.

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.
