Guild Wars Description
"No inherent effect. Many Mesmer skills, especially spells which disrupt spell-casting and deal direct damage, become more effective with higher Domination Magic."
Domination Magic is a very important skill for Mesmers, perhaps the most important. This attribute is the reason that spell-casters fear and loathe Mesmers. This attribute is linked to a large number of skills that disrupt the target's actions while dealing damage. One of the most popular of these is Power Spike, which deals a large amount of damage if the target foe is casting a spell. This skill has the dual purpose of dealing damage quickly, and stopping the spell from being cast entirely.
Domination Magic is also focused on punishing their foes for taking certain actions. Empathy deals damage every time the foe attacks, Shatter Enchantment deals damage when a foe has an enchantment active, Hex Breaker deals damage every time a hex is cast on you, Guilt steals energy if the target casts an offensive spell, Shame steals energy if the target casts a defensive spell, and Backfire deals a huge amount of damage if the target casts a spell at all.
The third use of Domination Magic is energy denial. Many of the skills linked to this attribute remove energy from the caster. Signet of Weariness removes energy from all foes in an area. These skills make a good combination with Mind Wrack, which deals damage if the target's energy ever reaches 0.
Domination Magic can be the most important attribute for a Mesmer, with more damaging skills than Illusion Magic and Inspiration Magic combined. When combined with Inspiration Magic for healing skills and Illusion Magic for the various effects it places on foes, the Mesmer can be a deadly weapon indeed.
