This feature is unlocked through Ascension

Portals are an essential part of progression, most Quests can only be completed by going to different Dimensions.
Once you travel to a new Dimension through a Portal, you will stay there until you go into another Portal.
Neither ascensions nor the portal cooldown change the Dimension you are currently in.
The Portal Cooldown can be reset by paying 5 Jewels of Soul.

Portal Cycles

Portals are randomly cyclical. Each cycle includes every unlocked Dimension except Bonus Stages, but the order within the cycle is random. Skipping/Missing a Portal will count it as having appeared within your cycle and will not show up again until that cycle concludes.
It is not possible to get a Portal leading to the Dimension you're already in. In this case that Portal will also automatically be skipped.
When purchasing a new Dimension, it will be added to the next cycle, so it could take you a few Portals to find it.
