PS - WANDS HAVE CRITICAL DAMAGE.

Note: When you class change Elementer's skills will only work if you have a Staff equipped while Psykeeper's skills will only work if you have a Wand equipped.

Upgrading:

Upgrading becomes extremely important for Mages/Elementers/Psykeepers when they want to compensate for a specific weakness that comes out of their build. (Either a weak defense or weak damage and low mana pool) Most of it can be solved by upgrading or enchanting your armor and weapons.

PXP:

PXP is the bar at the bottom of your EXP bar. When you use a skill your PXP decreases. This means that your store of PXP is transferred to the EXP of the skill that you used. You get PXP by killing monsters. When you die you start out with 0 PXP after you kill a monster, or a few monsters, your PXP bar will fill up. As long as there is some XP in your PXP bar, your skills will gain experience. PXP is needed to level up skills.

For example your PXP is 100% and the level of your Fire Strike is 6 at 0.0%. After you use Fire Strike, PXP decreases for about 2.5% leaving you with only 97.5%. While your Fire Strike is now at level 6 with 2.5% of experience.

IMPORTANT: This is just an example the values aren't exact, I'm not sure what the exact numbers are but this is the general idea. It is very important for Mages to understand this because Mages are highly dependent on skills.

In addition to that, at your skill menu, when you click on a skill you will see its name, level and the amount of exp that it currently has for that level. At the left side of these things there is either a ^ sign or a - bar sign. The arrow sign pointing up means that your skill is ready to increase in exp and you want it to level up. If it has a - bar sign then it means that the skill is barred from getting more exp. You can change this manually by clicking on the icon. There are reasons why you'd want to stop levelling up a skill which I won't discuss here.

Note: The experience you get from monsters is what fills both your PXP and EXP. So filling up your PXP bar takes away a bit of the EXP you get from killing monsters. This is miniscule at higher levels.

Level Gap:

I'm not sure if that's what this is officially called but it has been coined as such by the Flyffinos. In Flyff penya if you face off with a monster stronger than you by a great level gap, you tend to deal no damage or at the very least weaker damage. The higher the level of the monster in comparison to your level, the greater the gap, the greater the decrease in damage you're able to do and vice versa. Please note that a difference of two to three levels matter immensely. Especially for Mages because the level gap tend to affect skills more so than normal attacks.
