Sea Vendor Sia

3★ UniqueWaterSupportBasket

A 136-year-old mermaid merchant who's peddled her wares everywhere from the sea to a floating sky castle.

A mid-tier Unique Water-type Support — no specific meta write-up found this pass; placed by the game's own grade ladder rather than researched individually. Flag for a top-up once per-hero signal exists.

Recommended build

Ocean's Tear is Sia's Exclusive Weapon — equipping it is usually the single biggest damage or utility jump available, well beyond a generic weapon of the same type.

Support

Exclusive Weapon

Ocean's Tear

Each one's unique Weapon Skill sets the ailment this Hero brings to a Chain Skill chain — see the Weapons page for which.

Accessory

Necklace of BlessingUnique (3★)Heal + Weapon Skill Regen Speed — keeps skill uptime high

Ancient God RingRare (2★)Damage Reduction if the Support keeps dying before it can act

loadoutgg pick from the game's own accessory pool — Guardian Tales does not lock an accessory to a Hero, so this is a role-based call, not an in-game pairing.

Stats. HP/Defense for survivability first — a Support's damage numbers matter far less than staying alive to keep buffs and heals active.

Relic gear: Skill Damage rolls — a Support Hero's value comes from Leader Skill/buff uptime, not raw combat stats (per the progression guide's Relic-gear guidance).

Skill

Aqua Bubble

Pops water bubbles at range, or tosses a healing bubble to the lowest-HP ally that also cleanses them.
