Note on Dexterity and blocking:
If you adjust the formula, you can achieve blocking equal to total blocking of you items by using this formula:
DEX = (clvl * 2) + 15
This means that if you have a Homunculus, you will have 72% chance to block so long as your dexterity is double your character level plus 15.
This is actually the easiest way to maintain max block without having to spend 5 pts. into dexterity every so often. At level 6, start placing 2 stat points into dexterity and placing the rest in either vitality or strength. If you want max block, you can always hold on to those +dex charms that seem to be everywhere in the beginning of the game. Or you could just have a good shield with near 75% block and a safety amulet. Anyway, this is the trick I use for stat point allocation. I would say that for the first 4 levels, pump strength, then start the dexterity pumping in conjunction with vitality and strength.
