Harumasa Drive Disc Build

Best Drive Disc sets for Harumasa

Harumasa's best 4-piece set is Thunder Metal. Shadow Harmony is the alternative.

1. 

   Thunder Metal Best in slot

   4-piece: As long as an enemy in combat is Shocked, the equipper's ATK is increased by 28%

   2-piece: Electric DMG +10%. Drops from Hunter and Hound.

2. 

   Shadow Harmony

   4-piece: Upon hitting an enemy with an Aftershock or Dash Attack, if the DMG dealt aligns with the equipper's attribute, the equipper gains 1 stack of a buff effect, at most once per use of a skill. For each stack, the equipper's ATK increases by 4%, and CRIT Rate increases by 4%. The effect can stack up to 3 times and lasts for 15s. Repeated triggers reset the duration

   2-piece: The DMG of Aftershocks and Dash Attacks is increased by 15%. Drops from Gunslinger vs Guardian.

2-piece options

For the 2-piece slot the bonus matters, not the set's name. Several sets share the same 2-piece bonus, so Harumasa can take it from whichever one you have spare pieces of:

• ATK +10%: any of Hormone Punk or Astral Voice (they give the same bonus)
• CRIT DMG +16%: Branch & Blade Song
• The DMG of Aftershocks and Dash Attacks is increased by 15%: Shadow Harmony
• CRIT Rate +8%: Woodpecker Electro

Harumasa main stats: Disk 4, 5 and 6

Disks 1 to 3 always roll HP, ATK and DEF as their main stat, so the choice is on 4, 5 and 6. A > means "better than"; = means the two are about as good.

Harumasa substat priority

Roll for CRIT Rate and ATK% first. A disc showing neither of those is rarely worth levelling for Harumasa, whatever else it has.

1. CRIT Rate (until 75% in stat screen)
2. ATK%
3. CRIT DMG
4. PEN
5. Flat ATK

Where to farm Harumasa's Drive Discs

Thunder Metal drops from the Hunter and Hound Area Patrol stage. The other set it drops, Shockstar Disco, is not part of Harumasa's build.

Building more than one agent? The Area Patrol Recommender ranks every stage for your whole team at once, and the Drive Disc Stat Guide says which drops to keep while you farm.

Cordis Germina S-rank, CRIT Rate sub-stat

Cordis Germina is a near perfect match for Harumasa, with all of its universal Electric DMG Bonuses applying to him in full. Although they do need Basics to upkeep, Falling Feather (the aimed shot) and Ha-Oto no Ya all count for this, not to mention that the DEF Ignore on it is particularly valuable owing to it being relatively undiluted.

Skills to level first

1. Dodge
2. Chain Attack
3. Special Attack
4. Basic Attack
5. Assist

Agents who also use Thunder Metal

These agents compete with Harumasa for the same set, which is worth knowing before you hand a good piece to one of them.
