Arcane
Lufia 2 had an optional dungeon called Ancient Cave. Whenever you started this dungeon you were brought down to level 1 (you get your levels back when you exit) and lose all your items (also get them back when you leave) and you had to find everything from scratch making for a pesudo-roguelite. This would be really fun in a game with more varied character building options, but as far as I know the only thing to copy it was a Final Fantasy V romhack (which is good and shows how it can be fun in a game with more variety).
