Last Epoch currently has dungeons which have different difficulty tiers, from tier 1 up to tier 4 as of now, and the Monolith of Fate.
The MoF functions similarly to Diablo’s rifts, or I suppose a less clunky version of Grim Dawn’s rifts too.
You go into a map, kill a bunch of enemies and complete some basic objective like capturing a point, surviving an ambush, or killing a boss, and you leave. Rinse and repeat while you farm nearly a dozen different monolith islands, each with their own end of path boss which has it’s own drop table.
Each island also gives different blessings, which function as character-wide buffs you can obtain from killing said island bosses, each with a range of % stats, some give increase drop chance for a particular type of item, others give huge buffs of resistances or crit avoidance.
After you clear all monolith bosses you can Empower your MoF, which basically just unlocks a Master-mode that starts all islands at level 100 where you can scale it’s difficulty endlessly, theoretically.
I say theoretically cause in order to increase difficulty and loot-drops you need higher corruption levels, which you need to clear maps, find a node for the Shade of Orobyss boss, kill it, and repeat. Each time it’s killed your corruption for that islands also goes up. Most builds that aren’t super meta min-maxing nerds typically shoot for between 250-400 corruption for endgame, but some builds have definitely gotten much higher than that.
There’s also arena, but that’s very self explanatory. It’s an endless PVE-fest where you kill as long as you can, and it’s not really my favorite thing to do.
I love Monolith farming and dungeons. MoF is like a more advanced version of GD’s and Diablo’s rifts, while dungeons are very similar to Grim Dawn’s roguelike dungeons where you get a key to enter, you die or leave the dungeon and you need a new key.
Dungeons also have amazing gold sinks as well as the means to create Legendaries, which is the strongest item rarity in the game. It’s a purple Exalted item mashed into an Unique item that randomly takes on certain affixes of the former.
Is it endless content? No. Is it a fair bit already with more to come? Yes.
They have also promised new endgame content post-1.0.
