You can access alternate versions of certain maps through Quantum Instances.
Monsters inside a Quantum Instance move faster, drop more items, and respawn more quickly.
There are no entry fees, and there is no time limit for how long you can stay inside.
After closing a Quantum Instance, you must wait five minutes before opening a new one.
These maps are useful for leveling up and getting gold or materials. In the case of getting gold, in some instances you can get both liquid gold and objects with high sale value in the store.
If you want to level up, it is advisable to go to one of the Act 8 maps. Currently, the experience system is made so that it is more optimal to kill enemies five levels above or below your current level. Therefore, we recommend that you keep in mind that the enemies you fight to level up are at most 5 levels above (or below) yours in order to receive the maximum experience.
Upon entering, you will receive a powerful buff for the first hour of your daily time inside a Quantum Instance.
