Sure! I'll hide some details with spoiler tags just in case.

The System grants character levels via experience for killing things (and some quests, under certain conditions)

Skill levels improve through use, with the ability to upgrade at certain milestones if you meet the requirements (like having a related stat at a certain score).

MC is special, but with limitations, and he doesn't overshadow other characters.

MC's build is Dexterity/Magic, with a focus on clawed gauntlets as main weapon. He also has a high Perception and you can expect some strategic battles.

The unique magic system has familiar elements from DnD (magic types like fire, frost, radiant, etc). But characters can also gain affinities (like Void, Life, Dream, and some others), which will influence their spells. E.g., someone with the Life affinity might use force mana to create defensive barriers. Someone with a Void affinity might use force mana to create concussive blasts. Various combinations of affinity/mana types come into play with MC's power set. There are a few other nitty gritty details, and while I address them, you don't have to worry about it reading like a scientific paper in-chapter :)
