Corroded Plate BP

[Sammsquanch]

Does anyone know exactly what in Kael has a chance to drop a corroded plate BP? Obviously platehouse and arena mobs and 4 way and up. Anything else? I have personally seen the 2 giants closest to WL zone drop a corroded chain bp so I’m not sure I trust the wiki. Any input is appreciated.

These are all STORM GAINTS not the Frost GAINTS
Adjutant , Legionnaire, Sentinel, Trooper, Veteran, Armor of Zek, a guardian of Zek, and all of the NAMEed storm gaints also can drop them
