4-Piece Sets
Shadow Harmony
4-Pc Shadow Harmony is the most consistent due to it not being reliant on Shock anomaly or Hormone Punk's uptime to do the most damage. The set gives everything Harumasa needs on top of its near 100% uptime. At max stacks (which will be surely after your burst starts) you will gain:
15% Dash Attack DMG Bonus 12% Combat ATK Boost 12% Crit Rate
The other sets have their uses in Mono-shock team and/or Shiyu Defense Speedrun.
15% Dash Attack DMG Bonus 12% Combat
ATK Boost 12% Crit RateThe other sets have their uses in Mono-shock team and/or Shiyu Defense Speedrun.
Hormone Punk
The best 4-Pc set for high burst DMG builds outside of Rina Mono Shock Teams, on top of its 2-Pc 10% ATK bonus it grants a massive 25% Combat ATK Bonus when swapped on field when it's not on cooldown for 10 seconds.
Especially the best when you do not need the Crit boost from 4-Pc Shadow Harmony to reach 100%~ Crit Rate with Dash Attacks.

The two best 2-Pc options for Harumasa. Always being a damage increase, but your pick will depend on if you have her signature or not.

Mindscapes
Mindscape 1
Harumasa's M1 is a great extender for his burst dps windows allowing more stacks from your basic attack and your quivers shooting another arrow at the target. Allowing for some lethal setups with increased stacks and marks on the opponent. It is also a good mindscape for On-field Harumasa as it extends his dash attack combo further.
