I'm guessing Shields are guarantee evie cant die in one shot then.
I feel the need to respond to this.
Evies are terribly squishy, and they can definitely die in one hit fully geared. You probably see Evies die in Glas all the time, because that's a one hit that's basically unavoidable.
Normal attacks can only break through mana shields. If a shield is up, the attack will only consume the shields, even if there's only one.
Criticals break through and go to HP. In the event of a critical hit, an Evie gets hit hard. When most (competent) Evies die, they died to a critical.
They're also vulnerable to the many combo attacks, even if they don't critical, as getting stunlocked and killed from full to zero is a very real threat that is largely irrelevant in most other circumstances for other classes, except spears with mediocre defense and perhaps scythes. Everyone else can get out of pseudo-stunlocks more easily.
