Honkai: Star Rail Rin Tohsaka Build Guide: Kit Explained

Okay, so I’m really digging Rin Tohsaka in Honkai: Star Rail. Basically, she uses her skill points as fuel to build up this thing called Gem Energy, and that’s what lets her deal damage – the more energy, the harder she hits! She gets powered up whenever anyone on my team uses or recharges their skills. Once she reaches 15 Gem Energy or sees 7 skill points spent, her normal skill evolves into something way stronger called “Second Magic Experiment.” It’s a pretty cool mechanic, honestly.

She automatically attacks a random enemy using Quantum damage until she runs out of energy or there are no enemies left with health, repeating this up to 33 times. Her ultimate ability restores one skill point, makes enemies weaker by stacking 25% vulnerability, and provides a significant boost of 12 Gem Energy. Additionally, whenever she deals damage, she gains 4 Gem Energy and recovers skill points. This document offers an in-depth look at her skills, ultimate ability, talents, techniques, and other details.

Skill

Jeweled Sword Zelretch: Deals Quantum DMG based on Rin Tohsaka’s ATK to one designated enemy target.
Second Magic Experiment: Deals Quantum DMG based on Rin Tohsaka’s ATK to one designated enemy target. Then, consumes 3 points of Gem Energy to deal additional Quantum DMG equal to 90% of Rin Tohsaka’s ATK to one random enemy. This repeats until Gem Energy is less than 3 or there are no enemy targets with current HP greater than 0, up to a maximum of 33 times. When used, if current Skill Points are greater than 2, she consumes Skill Points until there are 2 points left, and gains 2 points of Gem Energy for every 1 Skill Point consumed.

Ultimate

Rin Tohsaka’s attack deals massive damage to a single enemy – 600% of her ATK – and moderate damage to all enemies – 200% of her ATK. After using her Ultimate ability, she restores 1 Skill Point for her allies and makes all enemies take 20% more damage for 3 turns.

Talent

Gem Magecraft: After entering combat, she gains 20 Gem Energy. When an ally target consumes or recovers Skill Points, she increases that character’s CRIT DMG by 70% for 2 turns. For every 1 Skill Point consumed or recovered, she gains 1 Gem Energy. If Rin Tohsaka possesses 15 or more Gem Energy or if current Skill Points are 7 or more, her Skill is enhanced into Second Magic Experiment.
Freeform Tohsaka Style: After Archer uses his Skill Caladbolg II to attack, if 3 or fewer Skill Points are remaining or if Caladbolg II has been actively used 5 times during the current Circuit Connection state, then Rin Tohsaka and Archer will launch a Joint Follow-Up ATK and recover 4 Skill Points for allies. This Joint Follow-Up ATK can only trigger once. The trigger count resets when Rin Tohsaka’s turn ends.

Technique

After using the Technique, gain 10 points of “Gem Energy” at the start of the next combat.

Passive Skills

Elegant Conduct: When Rin Tohsaka is on the field, increases the max number of Skill Points by 2. When entering combat, her ATK increases by 150.0%, and Quantum RES PEN increases by 15.0%. If Archer is in the team, Archer also gains this effect.
Ladylike Poise: When entering combat and after using Enhanced Skill, Rin Tohsaka’s SPD increases by 20.0%, lasting for 3 turns.
Inbound Prosperity: When Rin Tohsaka uses her Ultimate, she gains 12 points of Gem Energy.
