Hydroid Prime · The kit
Rain, dash, steal, kraken
Hydroid is a Corrosive pirate. Plunder is the 2026 kit — armor for you, Corrosive for your guns. Tentacles are the camp and the farm. Old Undertow videos will lie to you.

Deep Tendril
Enemies Hydroid damages become extra vulnerable to Corrosive status. The first Corrosive stack on them shreds more armor than it should. Barrage, Plunder, and a Corrosive gun all feed this. You want Corrosive on something.
Tempest Barrage
25–50Target a patch of floor and drown it in cannon-fire. Hold to charge a bigger, longer storm. Viral Tempest (augment) slaps Viral on every hit so you prime health and armor together. Common Helminth slot once you would rather Gloom or Roar than rain.

- Helminth
- Dump slot on Gloom / weapon configs
Tidal Surge
50Crash forward as a wall of water. You cannot be damaged in the wave. Enemies get slammed. Tidal Impunity (augment) grants status immunity to anyone you wash over — a better Rolling Guard you can share. On campy tiles this is the Helminth slot (Nourish, Breach Surge).

- Status cleanse + immunity
Plunder
75Rip armor off every enemy in range and wear it. Each target — and each Corrosive status already on them — adds Corrosive damage to Hydroid's weapons and abilities, capped by Strength. Rousing Plunder raises the cap and heals allies in Affinity Range. Recast on fresh packs. This is why you built Hydroid in 2026.

Tentacle Swarm
100A sea monster punches tentacles through the floor. Grabbed enemies flail and take damage. Duration and Range make it a Defense god. Pilfering Swarm (augment) rolls extra loot on tentacle kills — still one of the better farm buttons in the game. Charge it for a wider slam.
