Double Corrupt Life Implicit "6% increased life" = lose 100+ life instead.

Greeds Embrace. Double Corrupted with AOE gems, and 6% Increased life.

Put it on. Lose 6% life.

Put old Greeds Embrace back on, life stays normal.

Swap to different character and try it again, same chest, same issue.
The life implicit corruption is doing the opposite of what it should.

The life implicit modifier is doing what it says.

So is the life Mastery that gives increased max life if your body armour has no life modifiers.
