From a old game.

From Ragnarok aka Valhalla, the dead characters become ghost that can be encounter in a new game, and all their non-artifact items too.
The game as "red bag" a item with lots store, like the dimensional containers from other games.
Boats.
Skills can be learned from certain rare scrolls.
The screen where the ghost appear is at the same stage you left, mean : same amount monsters, items or disasters made with wands/potions, the savegame is necessary as far I know.

This game (Tales of Maj'Eyal) is GREAT! Cant believe I never ear of this before, I play and search for roguelikes for years and just found this one.

Ghosts could be interesting, perhaps. The game is random in nature, though, and making the dungeon the same as on a dead character would be all kinds of bad.

As for skill scrolls, this game doesn't have scrolls. If it still did, I'm not sure whether that would be such a good idea. There are already wearable times and quest rewards that do similar things, so another way of doing the same thing isn't necessary, I think.

not sure how ghosts would work in some dungeons either as they get "revamped" later... also this may cause the player to find really good items at a low level, depending on how this was coded.

Yes, maybe these are not the best ideas for this game, I always look for my ghost items in ragnarok for save some work. That dont fit here.

-How about make better gems from lesser ones? Like 3 lesser x 1 or 5 for 1?
-Some company? A few recruitables can be nice.
-Optional needs? Food, sleep?
-More craft options, can obtain materials same way obtain gems.
-Enable the crystals in the cave to allow mining some gem (for craft)
-Enable mining
