Regardless of your build, as a warrior you only need to follow the simple array of stats at every level up, 2 STR : 1 AGI You don’t need anything else~ so dun add anything else~ For every point of STR, you'll get 1 'damage'. Keep it high~
Stick with this till around 90 AGI then just add STR. If you want to solo/hunt later on, feel free to add more AGI at your own leisure, but by this time you’ll be with large parties and will always have buffs. For every pt of AGI, you get 1 point of accuracy; for every 2-3 points, you get 1 crit. Great for solo builds~
VIT is not so necessary at first, but again if you want to solo bosses or train in higher level maps early on, 20 VIT is probably enough to keep you alive well enough. Warriors get a whopping 60 HP per point of VIT.
Once you get to your 2nd Job, that’s a different story. We’ll get to that later~
