At a Glance
Strengths & Weaknesses
Rappa
- Ultimate “Nindō Supreme: Aishiteru” Enters the "Sealform" state—most of the kit’s damage lives inside that window, not on filler Basics.
- Skill “Ninja Strike: Rooted Resolute” hits every enemy on the field in one cast—this is the spend that keeps the rotation honest.
- Talent “Ninja Tech: Endurance Gauge” hits every enemy on the field in one cast—miss the stack conditions and the burst window feels empty.
- E0 without “Ninjutsu Inscription: Dazzling Evilbreaker” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Erudition carries—plan the cone before deep eidolon hunting.
- Rappa wants Break Effect supports and Toughness bars that can actually be broken; into awkward weakness line-ups the Complete Combustion / Break loop loses most of its damage.
- Spamming “Ninja Strike: Rooted Resolute” every turn without watching Skill Points strands the rest of the team—Rappa is often the SP sink.
Serval
- Ultimate “Here Comes the Mechanical Fever” hits the full field and forces DoT application/detonation in one cast—Pure Fiction waves melt once the status is seeded.
- “Lightning Flash” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “Galvanic Chords” seeds or detonates DoT statuses in the same cast—ignore it and Serval plays like a worse generic Erudition unit.
- If Energy or Skill Points starve “Here Comes the Mechanical Fever”, Serval spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
- As a 4★ Erudition unit, Serval 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 “Lightning Flash” every turn without watching Skill Points strands the rest of the team—Serval is often the SP sink.

Pela enables Super Break / Toughness pressure rather than a generic CRIT Harmony slot.
With Serval

With Rappa
