Spells

Spells are magical syntaxes that, once cast, will consume some mana or soul in order to produce the desired effect.
All spells require a certain amount of of resource every time they are used, and also have a minimum level requirement. In addition to these restrictions, some spells can only be used by certain vocations.
You cannot use spells too rapidly, as the client will tell you that you are exhausted if you cast spells too quickly in a short period of time. Note that you will not get muted for quickly casting spells, but you cannot cast spells while muted.
