Strengths & Weaknesses

Rin Tohsaka

Strengths
  • “An Gal Ta Ki Gal Šè” hits every enemy on the field in one cast, so Rin Tohsaka stays relevant when MoC and Pure Fiction spawn multiple targets.
  • Talent “Gem Magecraft” buffs allies’ damage for a short window—damage keeps flowing even when Rin Tohsaka is not the active turn.
  • Skill “Jeweled Sword Zelretch” dumps a large single-target multiplier into one elite—this is the spend that keeps the rotation honest.
Weaknesses
  • Follow-Ups from “Gem Magecraft” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Rin Tohsaka’s off-turn damage.
  • E0 without “Flickering Stars” 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.
  • Spamming “Jeweled Sword Zelretch” every turn without watching Skill Points strands the rest of the team—Rin Tohsaka is often the SP sink.

Serval

Strengths
  • 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.
Weaknesses
  • 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.
