Hello, I need help. I don't have alot of life so... what school should i pick?
As your wizard levels up you can choose gear that helps with that. You usually must decide which is most important to you as gear gets more advanced but most all will include boosts for health and mana. Some pets can give you more also.
I'm a fire wizard and it took a little bit before I built up my health too. Pay attention to what clothes you wear. That can affect your levels. Also make sure you're carrying your knives and wearing your neck pieces and rings. All that stuff can help you.
