First the Champions must figure out how to get out of Elutrel with their lives intact, not an easy feat. Once down and fought clear of the blood war, the wastelands of Avernus and their warmachines are still treacherous at best...
Note: you will need to have completed the previous two Descent into Avernus Adventures, Eltruel has Fallen and Resolve Amongst Chaos, in order to access these new Adventures.

Into the Fire
We're in the depths of the High Hall in Elturel. Hell is all around us, and we need to find our way out and travel through the wasteland to Fort Knucklebone...- Variant: A Difficult Descent — Getting out of Elturel requires Strength and Dexterity. Only Champions with DEX and STR of 13 or higher can be used.
Reach area 300.
Dreamscape
Arriving at Fort Knucklebone, we learn the ways of Avernus before starting our dream quest with Mad Maggie.- Variant: Dream Gauntlet — Healing is harder in Hell. Only Neutral or Good Champions may be used. Champions do not heal to full nor are they revived when advancing areas. The only way to revive or heal defeated Champions is to go back one or more areas. If you go back one or more areas in your two highest unlocked areas, enemy damage is increased by 25% stacking multiplicatively.
Reach area 325.
