Cissia

Cissia's signature covers everything she wants: an Energy Regen main stat that feeds her Core Passive, one of the largest unconditional CRIT Rate bonuses available, and a big chunk of personal DEF Ignore. The 3-second buff ramps quickly and never decays while she is off-field, so upkeep only matters in on-field carry setups.

Orphie's signature is a pure stat stick, but a competitive one: S-Rank-level Energy Regen as the main stat plus a solid unconditional CRIT Rate bonus. It trails Cissia's own signature on CRIT, yet still makes her build noticeably easier to complete.

Anton may skip his own signature, but Cissia thrives on it. Beyond the Energy Regen main stat, its bonus is trivial to keep active through her frequent EX Specials and boosts Basic Attacks, which make up most of her damage, putting it on par with premium picks.

Seed's signature is one of Cissia's strongest picks for personal damage. You give up some team DEF Shred, but the engine's own effect claws part of that back. Its DMG and CRIT Rate bonuses suit a carry Cissia; if Seed is on the team, though, she gets more out of it than Cissia does.

A CRIT DMG-heavy stat stick. It sits behind other premium and even F2P choices, but it shines when CRIT Rate comes for free, such as with a P5 Gameball buff or teammate CRIT Rate buffs.
