In Corvus Glaive's description it states that as long as Glaive immunity is active, CG doesn't take damage from Cold Snap, Bleed and Shock debuffs. However, ever since variant was released, I noticed that even though he had Glaive charges, he was losing HP from shock damage.
And now in act 6 on the shock paths, he is degenerating despite having Glaive charges
