Now let's talk about Aura,
Aura user are in majority in world there are more than 70 % of the people are Aura user.
yes! the mana Affinity are that Rear And with this affinity, We can directly Absorb the Mana from atmosphere
But it not True For The Aura users They have either Refine the mana to Aura Trough There Aura Affinity (Aura Seed) in there Dantian or they have to absorb the Fragments of the Mana particals.
And Directly Refining The mana Partical to Aura they need to Bulid a dantian in there abandon, With this they can directly Rifine mana to Aura
So basically they had to absorb Fragments of Mana partical until there body Reach The limit of contain Aura Means Peck of the E rank (E+) with this step complete.
They had to do same thing as Mana user do but they have to build Dantian and the se time They had to Refining there body So it can become Stronger to Rifine the mana to Aura.
As for stages they had to Refining there body ech time they increase there level mad with this there dantian become Larger and Stronger.
G to E rank. :. Absorb the Mana fragment of mana Particals and make there body Stronger
D Rank:. Build Dantian in abdomen in palce if Aura Seed and Rifine your body
C rank :. Refine your bones and make Dantian Twise size
B rank :- Complete Metamorphosis (build a complete new body from body Refining and make Dantian increase size 5 times then privious)
A rank :- Make dantian 10 times than before and Rifine body more
S rank : Second Metamorphosis and Make domain
Ss rank :- enhance further In S rank
SSS rank :- ???
(this aplied to all race like Dwarfs ,humans ,Dark elf,Dami human)
(Other than Dark elf all the elf are born with Mana and also there 50-50 Ratio to they born Aura or Mana users)
So The thing is they can only Rifine mana when they build there dantian it means they become D Rank.
(speed of Refineing are depends upon there potential)
by the way Aura can make people body stronger
While compar to mana user there speed are slow because absorption of statment and from D rank they have to Rifine mana to Aura.and also they have to Rifine there body .
While mana user are can directly Absorb Mana so there speed are Fast and they also no need to
But for later stage There are benifit for the Aura user they Can easily Breakthrough to S lavel ,There speed will be increased when they become B Rank and for SS rank it same As Mana users.
While for mana user They are Fast under B rank but for B rank to S this is much more hard then Aura user because they had to increase there Mental power for spell,and increasing of Metal power are Hader then Body.as for SS rank it same as Aura user
Now Tham there Fighting powers.
The Aura user are Powerful in close combat and Midle Range and also they have powerfull body.There disadvantages are Long range and they can not attake multiple target.
While Magic user are strong in Medial and long range attack and thery are experts in multiple target.While there wickness are close range and theire body.
But now the magician also make there body stronger and also there exception Close combat mage and magic Swords man.
Also in Aura and Mana there are also Class are Make so much impect so we have to consider that possibility to.
And this come to end of the Mana Vs Aura
But there are always Exception,
Yes! One of the 5 protagonist, Alen Lionheart Son of Duke in Holy Empire. and this Duke are strongest Duke in Empire Second to the Emperor Yes you guess Write he was Second SS rank expert in Empire other then Emperor.
Alen Lionheart born with Both Affinity Mana mad Aura, yes he was one of the Monsters in 5 protagonist.
(note :monster means they are born with monsters talent)
Also people in this Empire also called him monster who Born With Both Aura and Mana.
