Hydroid summons the power of the ocean depths. Built around Tempest Barrage, Tidal Surge, Plunder.

Enemies damaged by Hydroid are more vulnerable to Corrosive Status, with initial Status reducing Armor by a percentage.

You want a tank / defense toolkit and Hydroid’s fantasy matches the mission.
Your squad is missing what Hydroid brings — especially Tempest Barrage.
You already own the mods / archon shards that make Hydroid’s scaling comfortable on Steel Path.

Tempest Barrage (Ability 1): Summon a tempest to rain down upon a target area.
Tidal Surge (Ability 2): Crash through enemies in a ferocious wall of water.
Plunder (Ability 3): Plunder Armor from nearby enemies and increase Corrosive Damage on your Abilities and weapons.
Tentacle Swarm (Ability 4): Summon a creature from the depths.

Tempest Barrage is often the Helminth sacrifice if your build never needs Ability 1 and you’d rather import a strip, buff, or survival tool.
Keep Tidal Surge and later abilities when they define Hydroid’s identity.
Never subsume the ability that enables the rest of the kit’s energy or survival loop.

Strength: Raises damage and effect potency across Hydroid’s Strength-scaling abilities.
Duration: Extends channeled / timed effects — often comfort on Hydroid if the kit leans on buffs or zones.
Range: Helps radius / targeting tools. Dump it if Hydroid is mostly self-buff or exalted weapons.
Efficiency: Keeps ability uptime comfortable, especially on longer Steel Path missions.

Match the priority to your main ability — Strength or Duration first for most kits, then Efficiency, then Range.

Mission / Context	Rating	Why
Steel Path Survival / Defense / Disruption	Excellent	Bring Hydroid when you want Tempest Barrage carrying Survival / Defense / Disruption tiles without a full strip team. Summon a tempest to rain down upon a target area. Hydroid summons the power of the ocean depths.
Mobile Defense / Excavation	Excellent	Point-hold missions reward Hydroid: Tempest Barrage turns the excavator into a killbox. Summon a tempest to rain down upon a target area. Hydroid summons the power of the ocean depths.
Exterminate / Capture Speed Runs	Situational	Usable on speed runs, but Hydroid’s tank / defense kit usually wants longer objectives than a 3-minute Exterminate. Summon a tempest to rain down upon a target area. Hydroid summons the power of the ocean depths.
Spy / Rescue / Nightmare	Weak	Loud kit. Leave Spy / Rescue to invis or silence frames; Tempest Barrage doesn’t make Hydroid quiet. Summon a tempest to rain down upon a target area. Hydroid summons the power of the ocean depths.
Open World / Bounties	Situational	Fine on clustered camps, but sparse open-world travel underuses Hydroid unless you love Tempest Barrage. Summon a tempest to rain down upon a target area. Hydroid summons the power of the ocean depths.
Long-Range Gunplay / Eidolon-Style Content	Weak	Hydroid wants pack clear or finishers, not pure long-range; Tempest Barrage won’t save an Eidolon-style loadout. Summon a tempest to rain down upon a target area. Hydroid summons the power of the ocean depths.
