Yeah, you'll kinda think you have uber gear, but believe me, you will find even better stuff deeper in Undermountain real fast. I do plan to drop a lot of stuff from Durnan's 'shop', and have been creating stores in Waterdeep instead-- a shop for swords, a shop for magic, a shop for shields.. each with unique stuff..
I am going to add a lot more quests very soon as well! Glad you're enjoying it! I will have a portal to Myth Drannor, as well as Evermeet! Lots to come!
