First off lets start out taking ALL the quests from Ella Foragehammer. She will be your Quest giver for this dungeon. Now if you receive a chest of your class you may speak with Ella and browse her goods to buy a key for vote points. The chest contain armor and other things you may need.
Once you loot the gear of your class you want to upgrade it. How this is done is by clicking the Upgrade Gem in your backpack and clicking on the (unequipped item) you looted from the dungeon. A quest like screen will pop up and give you a list of items you need to upgrade the item. This will require Depth Shards that you will loot off the monsters. You will need 10 shards to start then click the Upgrade Gem and the stack of 10 shards to make a Depth Stone. A Depth Stone is one of the items needed to upgrade your gear. The other is other armor that you can buy from the noobie vendor there in Crumbling Depths. The iron is given from later quest in the dungen or simply by going to magic stone/ quest zone/ Royal Exchange and buying for 1 vote point each.
Magic Gold- Magic Gold is a form of gold that is used for upgrading your weapons, armor or trinkets and rings. You can speak to the Nagga Located in Crumbing depths to find out how much you have. You receive 1 Magic Gold=MG for every one monster killed.
Once you have completed all quests and gotten all of your gear and upgraded it all your now ready to move to the next dungeon!
