A character’s Mana is displayed numerically and also in the large blue globe. If you are a melee character, this should be of little concern to you, but if you are a wielder, pay attention to this at all times. Mana is spent every time you cast a spell. If you run out, you won’t be able to cast spells until you acquire more. Overcharging can occur when you pickup more Mana than you are allowed to carry. The overcharged amount will steadily decrease until the normal maximum has been reached.[1]
