I know it hasn’t been a week yet (TBH it almost, has) but I thought this would be a good place to discuss the new Hydroid rework. I’ll leave my thoughts, as usual, in the comment!

Release date: 2014-04-09

Abilities (the wiki wasn’t updated with the new descriptions yet so I’ll do my best and write them myself when applicable):
(New!) Passive: Enemies damaged by Hydroid are more vulnerable to Corrosion Status, with initial status reducing armor by 50%.
Tempest Barrage - Target an area and call down a barrage of liquid fury.
Tidal Surge - Crash through enemies in a ferocious wall of water.
(Old)Undertow - Become a water trap and drown unsuspecting enemies.
(New!) Plunder - All enemies in range affected by Corrosive procs will have their armor reduced permanently while providing armor to Hydroid as well as adding bonus Corrosive damage to your weapons.
Tentacle Swarm - Spawn a Kraken that grabs and holds enemies while applying Corrosive damage and status.

Acquisition: Blueprint purchasable from the market, components drop from Councilor Vay Hek on Oro, Earth.
