Hmm, a built-in leveling system... you say it's quite elaborate? More so than Starfury? In Starfury you could do a base value and a linear increase or decrease per level, that's about it...
But Starfury does have a "Uses Levels" field in Main_Components.txt which you can set to false in order to disable the whole leveling scheme for any particular item, leaving it pretty much open to "templatizing"; does Dungeon Odyssey have the same field for its items and such?
