Water Magic

Water Magic is an Elementalist secondary attribute, meaning that any character with Elementalist as their primary or secondary profession can put points into this attribute.

Guild Wars Description
"No inherent effect. Many Elementalist skills, especially spells which deal cold damage and slow and hinder your foes, become more effective with higher Water Magic."

General Description
Though named Water Magic, this attribute mostly deals in cold damage and ice-based hexes. Water Magic is a very powerful attribute. While its spells may do less damage per hit than their Fire Magic counterparts, they usually slow down or hinder their targets in some way at the same time. Water Magic spells are also more versatile; there are quite a few skills that help protect the caster from harm.

For dealing damage, Deep Freeze, Frozen Burst, Ice Spikes and Shard Storm all deal large amounts of cold damage while at the same time slowing down foes. This is useful in many ways; it can be used to keep incoming foes from reaching the caster, or keep the targets from fleeing the attacks that follow.

In addition to typical damage dealing, Water Magic skills provide a versatile collection of negative effects to throw at the enemy. Water Trident is an extremely useful skill in PvP knocking down moving foes. Maelstrom interrupts any enemy spells being cast in its area of effect for its duration. Blurred Vision causes enemies to miss with their attacks.

One of the best aspects of Water Magic is the defensive boost it can give the caster. Swirling Aura helps avoid most projectiles. Armor of Frost and Armor of Mist boost the caster's armor, the latter even increasing his movement speed. Mist Form causes the caster to become invulnerable to attacks while Ward Against Harm gives party members in the area of effect a good general armor bonus as well as an additional bonus aganist fire damage.
