Strengths & Weaknesses

Rappa

Strengths
  • 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.
Weaknesses
  • 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.

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.

With Rin Tohsaka

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

With Rappa

Gallagher keeps Toughness routes alive with heals (and Break-friendly sustain when built that way).

With Rin Tohsaka

Gallagher covers healing so the carry can stay on-curve without a limited Abundance.
