First of all, it is really great that we finally have a new dungeon, let's hope some new content will make the server more active again.
Got a few suggestions, I think the drop rate of frozen orb is a bit to high. Got like 2 times as many frozen orbs as glacial shards. You can also up the glacial shard drops, but I think then eveyone will be maxed again within a week.
Then the bosses are pretty easy and only drop 1 shard too, maybe it's an idea to make the bosses almost impossible to solo ( so ppl can still farm on mobs when there is nobody to farm with, and make a group to kill bosses) and then make them drop like 20 shards or something.
Also I can't get pas sister Svalna, not abble to attack the boss for some reason.
