What is character builds?

I have no idea what this means. Is my character built good?

Character builds is a term used in games like guild wars, WoW, and morrowind even, etc.

It is practically just the choices you've made for your character, and the goals and purpose of the character. So, for example, a warrior class. They're usually tanks (Tanks take damage and distract the enemy from the ranged characters, and I reckon also some good damaging ability). They usually require a whole heap of health and armour, with a focus on being able to take or deflect lots of damage.

There are a variety of different styles and builds you can go with! It's also similar to Diablo 2 character builds. It's basically just the best way to allocate your stats, skills and items to achieve a certain goal.
