Rin Tohsaka's Kit

Rin Tohsaka's kit revolves around Gem Energy, a resource she gains when allies consume or recover Skill Points. With 15 or more Gem Energy or 7+ Skill Points, her Skill becomes Second Magic Experiment, an AoE attack that repeatedly hits random enemies.

Basic Attack: Bajiquan

• Deals 50% ATK as Quantum damage to a single target.

Skill: Jeweled Sword Zelretch (Single Target)

• Deals 90% ATK Quantum damage to one enemy.

Enhanced Skill: Second Magic Experiment (AoE)

• Deals 45% ATK Quantum damage to all enemies, then consumes 3 Gem Energy to deal an additional 45% ATK to a random enemy, repeating until Gem Energy is below 3 or no enemies remain (max 33 hits). If Skill Points exceed 2, it consumes down to 2 points, gaining 2 Gem Energy per point consumed.

Talent: Gem Magecraft

• Starts combat with 20 Gem Energy. When an ally consumes or recovers Skill Points, that ally gains 70% Crit Damage for 2 turns. Rin gains 1 Gem Energy per Skill Point consumed/recovered.

Talent: Freeform Tohsaka Style (Joint Attack)

• When Archer uses his Skill Caladbolg II under certain conditions (3 or fewer Skill Points, or 5 uses in current state), Rin and Archer launch a joint follow-up attack on all enemies, dealing 300% ATK each and recovering 4 Skill Points. Triggers once per turn.

Ultimate: An Gal Ta Ki Gal Šè

• Deals 600% ATK Quantum damage to one target and 200% ATK to adjacent enemies. Recovers 1 Skill Point and increases all enemies' damage taken by 20% for 3 turns.

Bonus Traces

• Elegant Conduct: Increases max Skill Points by 2. At combat start, Rin gains 150% ATK and 15% Quantum Res Pen (shared with Archer if in team).
• Ladylike Poise: After entering combat or using Enhanced Skill, Speed increases by 20% for 3 turns.
• Inbound Prosperity: Using Ultimate grants 12 Gem Energy.

Should You Pull?

Rin Tohsaka is a high-investment, high-reward Quantum DPS with unique team support through Skill Point generation. Her kit is built around Archer, making the pair a natural duo. If you enjoy Skill Point management and want a strong Quantum option for endgame content like Memory of Chaos or Pure Fiction, she's worth considering. However, she requires specific team members to fully shine—plan accordingly.

Conclusion

Pre-farming Rin Tohsaka's materials ensures you can max her out on day one. Focus on Sneering Harlequin, Cosmic Sandpit, and Conqueror's Will to cover her ascension and trace needs. Stay tuned for official numbers when version 4.4 drops on 2026-07-24.
