Zero Build Guide
Zero is the main character you start with, a permanent S-Class Cosmos Esper who fills the Damage role on paper, using Solid-type Arc compatibility. In practice Zero is an Esper Cycle enabler: their Skill completes a Cycle instantly, so they step in, cast it, and swap out.
Best Arcs

Day Off
Best-in-slot for Zero. It gives the energy most teams struggle to get, which is why it's usually the best pick even at M1, and it improves Cosmos damage for their burst rotation.

Fluff of Fearlessness
A battle-pass Arc with a CRIT Rate main stat that boosts ATK after the Ultimate. A good secondary option for a Skill-first playstyle.

The Rain That Shook the World
Provides the stats Zero needs for decent personal damage and for supporting the team through Cycles, while you save for better Arcs.

The Forgotten
A free, F2P-friendly A-rank pick while you save for higher-ranked Arcs.
