I need help finding a game I've been searching for quite a while, in a pinch the most notable things are:

It's a PC game, I started playing it about 5 years ago, give or take, it was a typical action rpg with various classes like warrior, rouge, priest, mage and a skill tree, most of the focus is on slaying monsters and gathering loot, the game plays in an isometric view and takes place both in dungeons and outdoors.

As a player, you start out in a settlement, which is basically a square surrounded by sharpened log walls and you have a small hut/house. Inside the house is a blue crystal, sometimes the AI attacks it and you must protect it at all costs. Inside the settlement there are also some generic traders, I guess the only notable one being a guy that sells you unidentified loot ( Basically a gamble, you buy equipment without knowing it's rarity tier )

There are also several other houses, inhabited by AI humans, which are divided in one of the same classes the player can choose from ( warrior, mage etc.), which can be raided. Usually there will be 1-2 AI's defending their crystal and they will keep respawning indefinitely until it is destroyed, same as the player.

Oh yeah, and the game starts out in a grassy terrain with skeletons as enemies I THINK after you leave the settlement for the first time, on top of that I reckon priest needed to use prayer or something to gain faith/mana points and the mage had a fire nova spell and a lightning ball spell ( Which created a stationary lightning anomaly that attacked every monster in range), if that's of any use.

I would greatly appreciate any help! I tried to describe everything I remember about it, however I think the game was quite unpopular back in the day.
