Now there is more here, lets start with Innate Abilities, these are abilities that every single awakened has, regardless of race, but you can only have one.
Each Innate ability has a Tiered ranking system based on Potential(NOT current power)
Innate Ability Tiers:
Tier-1
Tier-2
Tier-3
Tier-4
Tier-5
Tier-6
Tier-7
Tier-8
Tier-9
Tier-10
(Tier-10 being highest and Tier-1 being lowest)
Innate abilities evolve a maximum total of 5 times, at each of these milestones for Mana core rank:
1. B-
2. S-
3. SS-
4. SSS-
5. SSS+
Also, most awakened have lower tier abilities, some have combat ones, some have healing or support ones, some have ones suited to specific roles like tank, assassin, etc… When you cross into B-, that's when your innate ability evolves and gains a new name, the second time it evolves is when you hit rank S-, and from then on, it evolves every major rank until SSS+, meaning 5 possible evolutions possible for the innate ability(assuming you have SSS+ rank soul potential to actually hit the 5th and final evolution). Also some innate abilities to deviate or diverge based on the wielder's choices. (e.g., Pyrokinesis turning into Solar Brand vs Crimson Hellfire depending on morality, training style, or bloodline influence).
Now this is important, Affinities, affinity is always tied to your innate ability, for example, an Awakened with a tier-5 innate ability called Pyrokinesis is not going to have a water affinity, they would however have a fire affinity, and affinity is limited to 3 possible maximum.
Affinity rankings determine how aligned with your affinity you are, Rankings are as follows:
Tier-1
Tier-2
Tier-3
Tier-4
Tier-5
(Tier- 5 being highest and Tier-1 being lowest)
Also important to note, there are typically 3 types of combatants, martial artists that prefer fighting barehanded or with gauntlets, weapon wielders(think swords, spears, bows, etc...), and then mages, for martial artists and weapon wielders, they mostly use mana to strengthen their body, focusing internally, though of course. For Mages, the use mana externally, creating spells via complex mana circuits, this requires not only magical talent but the brains to handle the calculations as well.
Also another thing for affinities, it determines what kind of magic you can use, but is also useful for martial artists and weapon wielders since reinforcing their weapons with affinity based attacks makes them stronger, also isn't tied to mental calculations but instead martial/weapon techniques that are made for that affinity.
