A Break Effect carry with two Harmony units that raise Break damage and Weakness Break efficiency, and a sustain that keeps Break uptime rather than adding damage.
A single-target Break carry: one Harmony unit raises Break damage, one implants the Weakness he needs, and the sustain is the one that also breaks.
Break damage across a whole wave rather than one target, so both Harmony slots go to Break amplification and the sustain adds Break of its own.
Himeko follows up whenever an enemy is Broken, which turns the standard-warp Erudition unit into a Break team’s damage dealer at no pull cost.

Roll substats in the order Effect Hit Rate (Until 67%) > Break Effect (Until 220% or 250% For Iron Cavalry) > SPD > HP% = DEF%.
Trace priority is Talent > Skill = Ultimate = Basic. The Ultimate costs 130 energy, which is what an Energy Regeneration Rate target has to clear.
