Regarding the trait Dodge Area of Frosilka,
do you know if it applies to the whole team or only to Frosilka ?

Thanks

It's only for him. AoE attacks don't touch him, I guess that includes every kind of AoE like deny skills (for instance hackster's black hat skill). Official announcement

Thanks. It is then an OK monster, but definitely not OP.

Just to clarify, Frosilka is female

Monsters with this trait should dodge negative but positive too
