Warrior/Knight Help What Is A Good Warrior Build For Level 83-ish

I am a level 83 (almost 84) warrior. I quit MC but I came back just to check this out. I am really confused by some of these new things but I heard there are things called builds? That are sets of armor and certain skill points? So I need help with a good warrior build. Does anyone know what things I should get and upgrade for warrior earth and fire with lots of strength and some defense. And where do I get the armor as well if you can.

 

Yeah but i think builds are more for the higher lv players, like lv 90+. Just use the best items you have.

 

Focus on intel, mana regen, %spell dmg, water dmg
