What are SBs ?
Skill Books, also known as SBs, are used to level up your skill once it's M [master] (See: M Skills).
How to make my skill Master ?
In order to master your skill, you need to make it lvl 17--->20.
Depending on your luck, it may master on 17, 18 ,19 or 20 points.
How do i gain Skill Points ?
Each time you level up, you gain 1 skill point.
A simple formula to see your total skill points : LVL-1=TOTAL SKILL POINTS
I'm at 17/18/19 points and didn't master my skill ! How can i get my skill points back !?
The simplest way is to use 1/2/3 TOF (See: Tome Of Forgetfulness). Each can be obtained for 100-200k [more expensive for warrior TOFs]. Then you re-add your points to the skill [u may NOT master it too, and will need to try again].
You can also use "Skill Reset Scroll", from item mall.
NOTE: If you are 30-, just talk to Old Lady. Pay some money, and she will reset your skills & force.
I read an SB but my skill is still lvl 2 !
SBs can fail. They only have a 30-50% success chance.
You can use "Tome" instead of SB, it gives a higher success chance.
Also, you need more than 1 SB to reach the next skill lvl, as shown below :
Lvl1: 1 SB
Lvl2: 2 SBs
Lvl10 to G1: 10SBs
NOTE: You need to wait 24 hours between a SB and another.
You can use item mall to read a SB before 24hours, or to get almost 100% success chance [it may still fail, but MUCH less].
NOTE2: You CAN'T make a skill G at lvl7, even if the descriptions says it's possible.
My skill is G ! What do i do now ?
Now your skill is G [Grand Master] (See:G Skills), you need Soul Stones ! Each sells for 80-100k+, and they may fail too. As SBs, you need more Soul Stones as your skill lvl up.
Each Soul Stone takes some of your HKP [[[}-0011Tome Of Forgetfulness|Hostile Killer Points]]] off. After G10, it's P [perfect] skills (See: P Skills). It's the max !!! GRATZ !!!!!!
How do I obtain SBs ?
SBs drop from Metins, mostly.
They may also drop from the Demon King. The SB dropped is random, although the lower lvl you are, and the higher lvl the Metin (see: Metins) is, you may obtain more SBs. [3 SBs from 4 Metins, instead of 1/4 (this is only an example)]
