*MINOR SPOILERS*
The power system is fairly straightforward.
Skipping his name for obvious reasons,
[Occupation:] is basically for classification. For example, necromancer, assassin, mage, swordsman, etc.
[Race:] Race is also straightforward. There are many races in this novel, and human is just one of them
[Affinity:] is the magic affinity for elements like ice, fire, water, shadow, lightning, nature, earth
[Passives:] are things that happen in the background, like regeneration. You don't need to say regeneration or cast it like a spell for it to occur.
[SKILLS] are things that need to be actively cast
Now let's get into stats
the first thing I should mention is that stats use letters to order them
the letters S, A, B, C, D, and F are used, and each letter can have a plus symbol, a minus symbol, or nothing in front.
The way MC gains stats is by completing quests. Quests do not give stat points that can be allocated anywhere; rather, quests give appropriate stats to corresponding stat categories.
Let's talk about each stat and what it means
STR or strength indicates MC's physical strength
MAG or magic indicates MC's ether capacity
DEF or defence indicates MC's ability to tank hits and his stamina
AGI or agility indicates MC's physical agility
INT or intelligence indicates how strong the MC's magic attacks are
and LUCK indicates how the world favors MC
Okay, this pretty much sums up the power system
