Rin Tohsaka | Honkai: Star Rail

Overview

Rin Tohsaka is a specialized Archer support / sub-DPS who fixes his biggest weakness: Skill Point economy. She is extremely strong with Archer, but much less valuable outside that pairing at E0.

Role

Archer Enabler / Sub-DPS

Playstyle

Let the team spend and recover SP to build Rin's Gem Energy. Use her Enhanced Skill when you have enough resources, but prioritize keeping Archer supplied with SP and triggering their Joint Follow-Up consistently

Why It Works

Every SP spent or recovered generates Gem Energy and buffs CRIT DMG. With Archer, Rin also shares 150% ATK + 15% Quantum RES PEN, while their Joint Follow-Up restores 4 SP, letting Archer continue his Skill chain.

Watch For

Don't drain the team's SP with Rin right before Archer acts. Rin needs opportunities to finish her turn between Archer rotations, since the Joint Follow-Up trigger resets at the end of her turn.

Playstyle

Combat Flow

Build Gem Energy → Archer spends SP → Joint Follow-Up → recover 4 SP → Rin acts, using Enhanced Skill when safe → Rin's turn ends/reset → repeat.

Key Notes

For support/sub-DPS Rin, roughly 135–160 SPD is a good range. ERR is also valuable because her Ultimate costs 160 Energy
Their Joint Follow-Up deals AoE damage and restores 4 SP
The Joint Follow-Up trigger resets when Rin's turn ends.

Build & Investment

Light Cones

Primary

Flickering Stars

Signature option tailored to her modern Erudition damage loop.

Alternative

Into the Unreachable Veil

Strong premium general Erudition alternative.

F2P

Eternal Calculus

Accessible multi-target ATK and speed option.

Relics

Primary

Genius of Brilliant Stars

Reliable Quantum set in relevant weakness and DEF-reduction matchups.

Alternative

The Ashblazing Grand Duke

Requires Archer for Rin's named Joint Follow-Up; its repeated damage instances build ATK stacks. The previous stacks reset when her next follow-up begins. Without that pairing, use another set.

Planars

Primary

Penacony, Land of the Dreams

For Archer support: grants Rin Energy Regeneration and boosts other Quantum allies, including Archer.

Situational

Tengoku@Livestream

For a main-carry build: gains extra CRIT DMG after at least three Skill Points are spent in one turn.

Recommended Substats

ATK%

Tune SPD for the selected role before balancing CRIT and ATK, counting Ladylike Poise's SPD buff. A main-carry setup with Action Advance can stay slower; a supporting Rin needs timely turns to reset her Archer joint-attack trigger.

Eidolon Investment

E0 includes Gem Energy, Skill Point recovery and the named Archer interaction. E1 supports repeated large Enhanced Skills, while E2 amplifies allied Skill damage; choose around whether Rin is the main carry or supporting Archer.

Flickering Stars adds CRIT Rate. When one ally character consumes at least four Skill Points in one turn, Radiant Crown grants team DEF ignore and increases Rin’s Skill damage for three turns. Plan that trigger around the team’s Skill Point spending.

An Enhanced Skill consuming at least 30 Gem Energy stores Shadow Gem for a later Enhanced Skill that does not spend Gem Energy or convert Skill Points.

Adds 30% personal Skill damage and makes all allies' Skill damage deal130% of its original value.

Teams

Recommended Teammates

Archer

Archer's repeated Skill Point spending generates Gem Energy. Their named joint attack restores Skill Points, and Rin's Elegant Conduct also buffs Archer.

Cerydra

For a main-carry Rin, Cerydra's Peerage duplicates an enemy-targeted Skill. Align it with a high-Gem Enhanced Skill rather than spending the copied attack on her ordinary Skill.
