Strengths & Weaknesses

Arlan

Strengths
  • “Frenzied Punishment” dumps a huge single-target Lightning multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
  • Skill “Shackle Breaker” spends HP as a deliberate self-damage cost—this is the spend that keeps the rotation honest.
  • Talent “Pain and Anger” Based on Arlan's current missing HP percentage—miss the stack conditions and the burst window feels empty.
Weaknesses
  • HP-spend skills mean Arlan 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.
  • As a 4★ Destruction unit, Arlan is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
  • Spamming “Shackle Breaker” every turn without watching Skill Points strands the rest of the team—Arlan is often the SP sink.

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.
