Build Notes

Prioritize Energy Recharge and ATK% for maximum battery utility. Secondary stats in Crit Rate/DMG for personal damage contribution. Signature weapon is best-in-slot for maximizing her support capabilities. Use Ultimate before Skill to bank the instant cycle. Zero's Insta-Cycle demands a team that exploits the guaranteed Blossom proc on demand.
