Evocation

Evocation is the school of arcane magic that deals with the direct manipulation of arcane energies. Typically, such control is employed offensively against a target or area through the use of of elemental blasts. A mage who specializes in evocation is called an evoker, though due to the aggressive character of the school, many pracititioners are known as battle- or warmagi. Others specialize in a single element, and are referred to as pyromancers, hydromancers, etc.

Elements
All evocation spells use one or more element to cause their effect. The most traditional elements for mages, particularly those of the Eastern Kingdoms, are fire, frost, and arcane. Less common elements employed by mages include nature (including lightning, earth, poison, etc) and shadow (such spells often are combinations of evocation and necromancy).

Casting Evocation Spells
When cast via typical techniques (as opposed to exotic methods like runecasting), a mage focuses simultaneously on a form and element for the spell to take. The mage draws on her mana to manifest to spell, weaving the elements to be used into the mana and then unleashing i

t. While all magic requires focus and concentration, with evocation it is perhaps especially important. This is because evocation spells are usually cast in situations of great stress or danger, often when the mage is under attack. Casters who routinely find themselves in such circumstances often prepare by maintaining constant focus, so that doing so becomes second nature and hence easier in the heat of battle.
