The domain of Air focuses most heavily on powerful single target attacks. Lightning also conveys the added bonus of a percentage of armor penetration factored into its damage, making it more effective against heavily armored foes - particularly Warriors, which this line is most suited for dealing with. This is especially true when one considers how easily one can blind their foes with Air magic - a condition that is devastating to classes that rely on melee attacks to deal their damage.

The domain of Earth deals primarily with strengthening the defenses of the Elementalist. These defenses may be spells that only target the Elementalist casting them, or they may be Wards - an Area of Effect spell that is beneficial to all of your allies. In the middle of a heated fight, having the right Ward on your side can quickly turn the tides of battle in your favor. Earth magic also contains a few odds and ends for offensive magics, including projectiles and AoE spells, though not enough in and of themselves to make an offensive Earth Elementalist as viable as an Air or Fire would be. As such, Earth is recommended to be used as a 'support' attribute.

An important attribute for all Elementalists, and often the reason why many people choose to make an Elementalist Primary (and secondary class the other profession they wanted to play.) Every point invested into Energy Storage increases the maximum amount of Energy the character has. Since all casters, especially Elementalists who often have very costly spells, rely so heavily on Energy, it is worth it to put as many points as can be spared into this attribute. Energy Storage also contains the Elementalist's self healing spell, so not only will you be able to cast more, you'll be able to keep yourself alive longer while doing so.

The domain of Fire is where most of the Elementalist's AoE offense resides. Fire magic is capable of striking multiple foes around your target, it can be used to damage anyone who enters a targetted area, or it can be used for single target strikes. Most offensive Elementalists are of the Fire element because of the good damage and diversity that the skills represent. They can also easily set foes on fire - a condition which is useful, since it ignores any type of armor or resistance in dealing its damage. While Fire contains some of the most powerful skills in game, these skills are often accompanied by a hefy Energy cost, so good energy management is a must.

The domain of Water is the Elementalist's 'utility' line. There is a large variety of benefits that can be reaped from this line, including defensive self buffs, wards, hexes, and perhaps most importantly - snares. A 'snare' is an attack that stops or hinders an enemy's ability to move, and the uses of this can be two fold: either to keep fleeing enemies from retreating, or to keep attacking enemies from approaching. Since most Elementalists rely on being at a distance to attack, having a means to keep your foes from closing in on you can be exceedingly useful. While not as strong as a focused Air or Fire Elementalist would be, a primary Water Elementalist is still a viable choice, due to the usefulness of many of their skills.
