Whaddya mean [Hydroid] ain't 'viable' for plunderin'?

To conquer Land and Sea, whilst giving you the optimal ability to pilfer and plunder; I bring you [Hydroid Prime].
Boasting armor and health, resistance to Tau, short range skills, with everlasting duration and enough strength to make the normal star chart a breeze.
You won't run out of energy anytime soon, especially if you add on Arcane Energize.

Notes:

• Three Umbral Mod Build, but only requires 2 Umbral Forma
• Low Range, High Duration, means your tentacle swarm will last for nearly an entire minute- for 35 energy.
• Tidal Surge propels you forward as fast as tides ride and fall.
• Undertow is free invincibility, so long as you are not inside any Nullifier bubbles. Use this to rejuvenate.
• Arcane Tanker can give you a ridiculous amount of armor, should you need it. It's also fun to use the Mauselon.
• I suggest replacing Tempest Barrage with Pillage- You'll keep the pirate theme, and gain a significant boost to survivability. Press 1 to recover shields.
