Underkeep Portals: Activate a Return Route

Activate a portal when you encounter it, then verify what destinations the game actually offers. Seeing a stone in a room is not the same as establishing a usable return route.

What the sources establish

The April 2026 developer update announced functional teleportation gates across the world. The current player guide describes touching portal stones and traveling between activated portals.

That supports fast travel as a system. It does not establish a portal at every named location or a way to escape every combat state.

Establish the route

1. Approach and interact with the portal stone when it is safe.
2. Watch for the activation response described by the game.
3. Open the available destination choice and check which routes are actually listed.
4. Leave a map note that distinguishes activated and unactivated sites.
5. When planning a return trip, check the destination before leaving the current area.

Use the visible interface rather than guessing a destination from a community map in another version.

Plan a purposeful return

Fast travel is especially useful when a new tool or key answers an old map note. Before traveling, check that the required item is present and that the old task has not already been completed. Bring the supplies needed for the area beyond the destination.

Limits

This guide does not publish portal coordinates, unlock order, combat-travel permissions or a guaranteed path to a Revival Statue. Those details need specific current evidence. A portal is a travel tool, not a promise that the party arrives fully healed or that every nearby enemy is gone.
