Harumasa
Who is Harumasa?
Harumasa is an S-rank Electric Attack agent from Section 6 with a unique arrow-based combat style. He is an on-field Electric DPS who excels in Stun-window burst damage — during Stunned enemy phases his charged arrow attacks deal greatly amplified Electric DMG. While not the highest ceiling Electric DPS, his distinctive playstyle and accessibility on rerun make him a viable choice for players building Electric teams who already have Trigger or Qingyi for Stun support.
Kit Summary
Charges and releases arrow shots that deal multiple Electric DMG hits; full-charge shots during Stun windows deal amplified damage.
Fires a rapid series of Electric arrows; resets charge stacks for an immediate full burst follow-up. Core damage ability.
On dodge assist, rapid Electric multi-hit arrow sequence — good for maintaining charge rhythm after defensive inputs.
Large area Electric burst dealing high damage and applying a stacking Electric vulnerability to enemies that amplifies follow-up arrow damage.
Build Guide
🔮 Best Relic / Echo Set
Thunder Metal (4pc) — Electric DMG Bonus + additional Electric DMG on hit. Best-in-slot for maximising his arrow burst damage in Stun windows.
⚔ Best Light Cone / Weapon
Signature W-Engine (Section 6 series) — ATK% + increases charged arrow DMG during Stun windows. F2P: Cannon Rotor (4★ Attack W-Engine) — strong ATK stat stick; Harumasa's Stun-window multipliers carry most of his damage independently of W-Engine.
📊 Substats Priority
👥 Best Teams
Electric: Harumasa + Trigger + Rina (Trigger Stuns for arrow burst windows; Rina Electric pen debuffer)
Budget Electric: Harumasa + Anby Demara + Rina (Anby covers basic Stun; Rina supports; fully F2P except Harumasa)
F2P Verdict
Harumasa is a limited S-rank but his team works with several standard/4-star units. Anby Demara and Rina are both accessible without limited pulls.
He performs best with Stun support — without Trigger or Qingyi, his damage drops meaningfully.
For new Electric team builders, Yanagi (Anomaly) or Trigger (Stun) may be better first limited purchases depending on playstyle preference.
Frequently Asked Questions
Is Harumasa viable without his signature?
Yes — Cannon Rotor (4★) is a workable budget option. His damage in Stun windows is primarily gate-kept by CRIT stats and team Stun uptime, not the specific W-Engine.
How do I maximise his arrow damage?
The key is ensuring enemies are in Stunned state before spending his full EX Special and charged arrows. Use Trigger or Qingyi first to bring enemies to the Daze threshold, then swap to Harumasa for the Stun-window burst.
Is Harumasa or Yanagi better for Electric teams?
Different roles — Yanagi is an Electric Anomaly DPS who pairs with Trigger for Disorder damage. Harumasa is an Attack DPS who needs Stun support. Both are viable; the choice depends on whether you prefer Anomaly or Attack playstyle.
