The Portal Prison is an ingenious invention of King Sigurd's mages. This is a magical trap the undead are lured into. Once inside, Hel's servants can no longer escape. But the Portal Prison gets crowded too quickly, and that's where the skills of immortals will come in handy.

You can enter the Portal Prison via a magical portal at Army Camp. You can enter the portal alone or in a squad.

The Portal Prison's layout changes every time you enter the portal. However, the Portal Prison always consists of four floors, and on the last one, the prison master (boss) awaits you.

For killing bosses, you will earn Warchief's rating points, which will unlock individual rewards, as well as new difficulty levels for the Portal Prison. Please note that rating points are awarded only when defeating a boss at your current maximum available difficulty level!

If you enter the Portal Prison in a squad, rating points are awarded individually for each player, according to the highest difficulty level available to them.

At the end of each Portal Prison floor you will find magical crystals. Break them to obtain Hugr (a magical resource). Speak to the Elven Sage at Army Camp to unlock Power Stones or upgrade already available ones.

Attention! Your Hugr supplies will disappear when the "Portal Prison Clear-Out" event ends! The Warchief at Army Camp will tell you how much time is left until then.

Power Stones are special temporary artifacts that will help you in the Portal Prison. Upon entering each Portal Prison floor, you will be able to choose one of three random Power Stones to strengthen your character. Bring Hugr to the Elven Sage to improve the selection of Power Stones available for choosing in the Portal Prison.

If you wish so, immediately after entering the Portal Prison, you can purchase various consumables from the Elven Sage. Those consumables will facilitate your progression and help you fight the Portal Prison Curse, a dark aura that gradually weakens your character.

If you die in the Portal Prison, all your items will remain with you, but temporary items (such as Power Stones) will disappear.
