Just a friendly warning for you guys.
Theres a challenge inside the mountain that is very very cheesy, in a very bad way. It requires you to face a groups of enemies, 3 to 4 at time in different sectors of the area in a limited time.
The challenge it self is not hard, but the developers turn on the cheap death mode on this one. The challenge is near water, there are several ice archers, ice mages and ice abysm mages. All this followed by dropping ice shards that not only damages you but increases your chilling bar by a good amount. To make matters worse, the ice barrier can knock you out during the event.
I feel like instead of making challening, this area is nothing but cheap deaths all over the place.
