Fire Magic

Fire Magic is an Elementalist secondary attribute meaning that any character with an Elementalist for their primary or secondary class can put points into this attribute.

Guild Wars Description
"No inherent effect. Many Elementalist skills, especially spells that burn your foes or deal fire damage in large areas, become more effective with higher Fire Magic."

General Description
Fire Magic is a favourite for a majority of Elementalists, and it's easy to see why. In terms of ways to damage foes, Fire Magic has it all. In terms of doing anything else for you...Fire Magic can't help you there. Fire Magic skills get the job done, as long as the job is simply to obliterate your foes in as many ways as possible.

The most basic Fire Magic skills are the ones that simply do damage to one or more targets: Flare, Fireball, Inferno, and Flame Burst. These will be the ones you will use when your energy is low (Fire Magic skills require vast amounts of energy). Against tough foes, Fire Magic has some skills that set fire to the target: Immolate, Incendiary Bonds, Rodgort's Invocationand Mind Burn. Also, the nifty spell Mark of Rodgort causes a foe to start on fire whenever they are struck with any fire damage.

Now we get to the skills that really put the hurt on both your foes and your energy. The area damage skills Fire Storm, Lava Font, and Searing Heat cause damage per second to an area, while you continue to use your direct damage spells as well. Meteor and Meteor Shower both deal vast amounts of damage and knock down your foes, while Phoenix is basically a combination of Inferno and Fireball.

In conclusion, if you like to hurt people, you'll like Fire Magic. You'll need to look elsewhere for skills that help, heal or protect you or your teammates however. Another downside to fire magic is the severe drain it has on your energy. Only Flare costs 5 energy, while an incredible 4 skills cost 25 energy (Mark of Rodgort, Meteor Shower, Rodgort's Invocation, and Searing Heat). This means the fire mage can be its own worst enemy, quickly running out of energy and reduced to normal attacks.
