Question about classes

[Chichi]

Hi, I'm a entirely new player who has never really played SRO, I'm at level 36 but I've just been blindly doing quests and have no knowledge about the game and I've seen people with different classes walking around and being in parties or items being bound to that specific class and I've been really interested to know how do you unlock a class does, it like appear at some level or do I have to learn it if there's a thread already made for it please let me know.Also if anyone can give me some tips for leveling or just basic tips every starting player should know I'd be thankful.

so theres 2 races, european and Chinese, Chinese is confusing, Theres Bicheon, for Sword or blade, Blade is for Pure str builds, and Sword for Int builds, (idk where you've been putting your stats but I'd only pick one, I think theres a stat reset in the Item mall that you have to buy.)
Theres Hueksal which has 2 weapons, You'll find Flaive for strength and Spear for Int builds Spear builds would require you to put 1 level every 10 levels into str, so 3 points of str after you level 9 times, the 10th time you put 1 level of str (3 points). and then theres Pacheon-Bow thats a pure str build as well as they have high crit rates. Then you have Force set of skills, each element has its perks. just read the descriptions.
Now the clothing has benefits as to which type you want to use, Full armor set gives HP replenishment speed every time you use a pot i think, and it makes your character run slower, but it has high physical defense and low magic. Protector set has slightly less hp recovery speed, and some MP cost reduction per skill use. Garments reduce the maximum amount of MP cost per skill while making you able to run faster. Usually Str builds use Garment, Pure int use armor, or Protector.
You can upgrade your stuffs base stats by making your items + +,2+3,+4 etc
You can add blue stats which increase str and int parry ratio, attack rating, add mp and hp to legs, chest, and helmet only, those are the green stones, the pink ones change the base stat %'s high % means best quality for that gear's level.
Then theres seal of star, moon, and sun, star makes the base value +5, moon +10, sun +15
