Overview

Seth ranks among the top main healers, excelling in both powerful burst healing and team-wide purification. Though she is an Ancestral vassal and therefore harder to obtain, her unique ability to restore the team’s HP to a previously higher state—followed by a substantial heal—makes her the optimal choice when strong, reliable healing and full-team cleanses are essential.

Pros

Only unit that can purify debuffs

Best pure healer of the game

Ancestral

Cons

Can't seem to purify controls like sleep and freeze

Lacks utility aside from her purifying debuffs
