Sera guide and info.

Sera

Path-walking Keymaker

4★ ICE Fighter Melee

Analysis

Solid Fighter with consistent output. Her Lakrima Charge Special Skill provides good AoE. Competitive in World and Conquest; needs investment for Rift.

Tier Position

World / Path T1

Conquest T1

Dimensional Rift T2

Game Modes

World / Path T1

Sera's Lakrima Charge transforms her into a spinning AoE machine, which is very effective for clearing groups in World/Path. She's consistently good, though she's slightly outclassed by top-tier AoE specialists. Still a fun and competitive choice.

Conquest T1

As a Fighter with Balanced DMG output, Sera handles boss content well. Her damage is steady and her Special Skill adds burst when needed. She's not the most efficient option, but she's reliable and needs little hand-holding.

Dimensional Rift T2

Sera's Special Skill AoE is real, but her overall pace and damage output are a step below the best Rift picks. She benefits noticeably from Awakenings, and without them can feel slower than expected for a timed mode.

Pros

Lakrima Charge transforms her into a spinning AoE machine for group clears

Consistent and predictable damage output with no complex setup

Reliable Fighter for players who want steady contribution without micromanagement

Cons

Slightly outclassed by top AoE specialists in each mode

Notably weaker in Rift without Awakening investment

Damage ceiling lower than more specialized or higher-tier units
