Warrior AP Guide

Well, distributing Warrior AP is really simple... it's just that people make it harder than it really is. See, unlike all other classes, Warriors only have one required stat. Strength. It's also the main factor in damage. Now, since they only have one required stat, of course there's a catch. Dexterity or Luck is required, or you'll have next to no accuracy. All the damage in the world doesn't matter if you can't hit a Green Mushroom at level 30. Now, Dexterity is obviously the preferred choice, since it adds more Accuracy than Luck and also gives a small damage boost.

Personally, my idea is to do (0.4*MaxDmg)+(0.6*MinDmg) for a number slightly lower than your average damage. Then, look for a monster whose HP is around that number or a little lower. If you have enough Accuracy to hit it 100% of the time, you're good. If it's a monster you can mass kill with Slash Blast, average damage equal to 40-50% is okay, but remember that constant usage of SB can quickly burn potions, especially at lower levels. Don't forget to apply any modifiers from skills you're using and take monster defense into account if you actually take this advice.
