plans for the endgame

"Eternal Exile" endgame mode.

Take the idea of the fourth difficulty level as a series of randomized areas taken from anywhere in the game.
What I imagine then is this chain of areas actually being endless, offering no reprieve, and towns being replaced by a single 'hub' location to which only a scroll of Town Portal can take you.

Things like unique bosses, events and areas could be added, there could be some sort of 'Event of the Day' added from time to time, and story or story-like threads that briefly interrupt the randomness could be seeded into it, triggering randomly or at, say, a character's hitting lvl [xx].

This could of course make flat level difficulty work.
