Duchess Lilitu - A1 - Abyssal Invocation places her small shield over an already much bigger shield. Sometimes she does, sometimes she does not. 

Ideally, her shield should not erase any shield bigger than the one she is trying to cast. Please change it so Duchess only places a shield if her or the lowest hp ally has a smaller shield than the one Duchess is trying to place. 

WTR: I am in arena, I use my Valkyrie to place a large shield, Duchess uses her A1 and completely erases Valkyrie's shield. It only happens 50% of the time.
