You can enter a dungeon as a group with a maximum number of 3 members. When a match is found, you will be transferred to a lobby where you will wait for up to 3 minutes for the lobby to fill. Characters are immune to damage in this stage and can inspect other players inventories. It is important that you do not use up any of your important cooldowns here since they do not reset after you get teleported to the dungeon. Furthermore, do not drop your items or gear in the lobby, as other players can pick them up and if the match starts and your items are still on the ground, you will spawn in the dungeon without them.
Normal dungeons host Common and Elite grade monsters with an extremely low chance of spawning Nightmare monsters. They feature low drop rates for Epic items and extremely low drop rates for Legendary items. No chance for Unique items.
It is recommended to bring some Consumables or Utility to aid you in your adventure. Consider bringing a 3-stack of bandages or healing potions at the very least.
As of Alpha Playtest 3, gear pieces can now have base attribute points.
Consider buying cheap upgrades to your starter gear from the Merchants to boost your defenses and your attribute points. Starter gear is a tier below anything you can buy or find in the dungeon, so anything will be an upgrade.
A better weapon will enable you to dispatch monsters faster, this increased clear speed means you run less of a risk of taking damage and have more time for looting.
