Sena Pros and Strength

Sena's Character Overview

Piercing DoT Specialist

Sena is a durable and mobile attacker who specializes in Piercing and DoT DMG. Furthermore, she has access to effects that increase the damage enemies take, which significantly boosts the party's outgoing damage.

Applies Piercing DoT to a Wide Range

Sena deals damage via her [Bloodthorn Seed] debuff. When activated, it deals AoE Piercing DMG and applies the [Bleed] DoT. Focus on providing Sena with NRG so she can use [Scarlet Outburst] every turn.

Increases Enemy Damage Taken

[Wound] applied via Sena's Trait, her Aura, and [Crimson Covenant] all significantly increase enemy damage taken via Piercing DMG and DoT. When paired with other characters who also excel in these types of damage, Sena's drastically increases their outgoing damage.

Has Resolve and Damage Sharing

Sena is a highly durable attacker due to [Tether], which shares a percentage of the damage Sena receives, and the healing + [Resolve] effects from [Bloodforged Renewal]. However, she takes Piercing DMG when attacking and has no damage reduction effects, so be mindful of how to utilize [Tether] and supplying her with additional healing as needed.
