Looking for an RPG map

Level 1
Apr 8, 2021
I am looking for an old RPG map, made no later than 2007. You start off as a vilager or a peasant. You can change into a different class by finding certain artifacts which are dropped from boss monsters around the map, and bringing them to a guild buildings, and I think you also need to reach the max level. You can upgrade your hero's class two more times by bringing stronger artifacts, for example Acolyte => Necromancer => Lich. At a certain point, you can build yourself a mansion where you can hire additional units. The map is vertical and quite thin, uses Lorderon theme, and I think it does not use TFT assets.
The map is quite simple and does not use advanced scripting, but I remember liking it a lot
