There are three major categories of stats that each RF Online character has: combat PT, skill PT, and level. Skill PTs are covered here. Combat PT governs just how strong a character is and is broken down into 4 to 6 areas. Levels, unlike many RPGs, do not really have a major effect on how strong a character is - they raise HP, FP, SP, and PT caps only.

As stated above, combat PT is divided into 4 to 6 statistics, depending on your race. Every character has four standard combat PTs - short range, long range, shield, and defense. Accretians have one additional combat PT - launcher. Bellato has Force and Unit as their additional combat PTs and Cora has Force and Summoning as their unique combat PTs. Whenever you perform an action, the corresponding PT rises. For example, if you bash an enemy in the face with a hammer, your short range PT will go up.

Depending on a character's level and class, their combat PTs are capped at a certain point. As the character advances in level, their PT caps also rise, allowing them to become stronger and stronger. Unlike other MMORPGs, it is important that players do not rush through levels - they should keep their various combat PTs close to their caps whenever possible. Remember, levels do not directly effect how strong a character is - levels only raise PT caps. If a character levels too quickly without raising their appropriate PTs, they will find it extremely difficult to raise those PTs at a later time - maybe even impossible. This is known as "dead-ending" a character.
