RF Online - "The beginning to the new world"
Skills are an element that allows characters to facilitate strategic plays with more powerful actions including critical attacks and instant boosting of fundamental abilities.
There are four major skill sets including melee skills specialized for warrior classes, range skills for ranger classes, item skills embedded in actual items, and finally class skills, which can be used after the first promotion. Also, each skill has four levels in the increasing order of [Beginner], [Novice], [Advanced], and [Expert].
In RF Online, you can achieve a maximum of level 7 (Grand Master). (Excluding item/class skills) Points go up every time a skill is used and when the points reach a certain limit, the skill level increases by one.
Skills become stronger as they ladder up the level. Each skill has [Beginner], [Novice], [Advanced], and [Expert] levels where they must satisfy the conditions below in order to be used.
 Melee skills
Mostly used by warrior classes, melee attacks deal powerful damage. You can diversify your attacks because there are different skills you can use for each weapon.
There are two types of skills where buff skills amplify the abilities of the attacker with hard and accurate hits whereas offensive skills do greater damage to enemies.
 Range skills

Range skills are often used by ranger classes for striking enemies from long distances. Buff skills allow more accurate and distant attacks whereas offensive skills have impactful effects and damages, further divided into skills for bow classes and firearm classes.
 Item skills

Item skills are consisted of unique skills embedded in certain acquired items. For example, capes enable the booster skill so that a character wearing it moves faster as there are other specific items that possess different skills.
 Class skills

These are skills that can be used when a character is promoted to pure class.
Skills specific to each job title will corner enemies to death.
