Hydroid by progress

Progression path first. Specialist cards after. Each progression card is the peak you can run at that rung — not a second identity.

First Tide

Learn the frame.

Best for: Star Chart, first Hydroid, learning the rework loop

Plunder the room, dash through with Tidal Surge, rain Tempest Barrage. Tentacles wait until you mean to camp.

The 2023 rework made Plunder the kit. Old Undertow Hydroid is gone. Do not look up 2018 videos.

First Tide — Star Chart

First serious version.

Best for: Junctions through the Outer Terminus. Steel Path is the next card, not this one.

Plunder the room, dash through with Tidal Surge, rain Tempest Barrage. Tentacles wait until you mean to camp. Primed Continuity and Primed Flow are the first real upgrade — not Blind Rage.

The 2023 rework made Plunder the kit. Old Undertow Hydroid is gone. Do not look up 2018 videos.

Corrosive Corsair — Steel Path

Your first endgame-capable version.

Best for: Steel Path Star Chart, Circuit, first Archon. Helminth is the next card.

High Strength Plunder. Viral Tempest primes. Guns inherit a huge Corrosive bonus. This is 2026 Hydroid. This is the peak you can run the day Steel Path unlocks — galvanized / arcanes, no Helminth.

Plunder is a weapon buff, an ability buff, and a personal armor pile. That is the identity.

Specialist builds

Not part of the path

Same frame, different job. These are not missing rungs — they are optional identities once the path feels easy.

Steel Path3–4 FormaAdvancedMedium confidenceFarmingDisruptionShards optional

Kraken Room

Your first endgame-capable version.

Best for: Defense, Interception, Disruption, any mission where you stand still on purpose

Tentacle Swarm owns the tile. Duration and Range. Enemies flail while you Plunder and shoot.

Hydroid is still one of the best 'this tile is mine' frames after the rework.

Drowned Slow

Only if you actually need it.

Best for: Solo Steel Path, Eximus rooms, people who want Hydroid to stand in the puddle and live

Gloom over Tempest Barrage. Plunder strip plus a slow aura. You become a sticky pirate tank.

Gloom is the Helminth tank button. Hydroid already wanted to stand in a room.

Pilfering Depths

Only if you actually need it.

Best for: Farming runs, Survival loot, people who already own Nekros and want a second loot frame

Pilfering Swarm plus Plunder. Tentacles print extra drops. You still strip so the pile actually dies.

Pilfering Swarm is still a real loot tool in 2026. It stacks with boosters and a Nekros.
