The Aspen Dungeon is on a cycle, where it is 48 hrs open and then on cooldown for 48 hrs. The Aspen Dungeon unlocks at Level 72. You can send 5 heroes to the Aspen Dungeon. Once you have chosen your 5 heroes, it looks like any gear changes will not be applied.
There will be waves of enemies and for each wave you have to select a hero to battle it. Health is not regenerated between waves so this dungeon is in iron man mode. Once your hero dies, they cannot take part in the dungeon until the next one opens. You can choose "Skip the Battle" in order to skip the fight itself. The layout was changed in the 1.17.37 update.
After defeating each wave, you will be presented with a reward. There are 3 different rewards possible - a Chest, a Vagrant Merchant or a Potion. Chests can provide Gold, Spirit, Gems or Monster Materials. Vagrant Merchants will sell various things to you (the prices are dependent on which Vagrant Merchant you get). Potions will either heal or buff your hero.
There are currently 6 stages (Easy, Normal, Difficult, Nightmare, Hell, Death) with 100 levels in each stage and once you pass 50 levels the next time you enter the dungeon it will automatically smash up to your current check point. Check Points are at levels 50 and level 100 of each stage. So if you pass to Easy 98 the next time aspens opens you will smash the first 50 levels and start from Easy 51 until you are able to pass Easy 100.
