Illusionsâ€”Mesmers create illusionsâ€”mind tricks that manifest themselves physically. Most illusions are directed at a specific target, but anyone can see and attack them. They can only exist for as long as that target is alive and can only be dispelled by attacking the illusion itself. A mesmer can maintain up to three illusions at a time, with the oldest illusion being replaced by the newly created one. There are two types of illusions: clones and phantasms.
- Clonesâ€”Clones are illusions that look just like the caster, have the casterâ€™s name, and have basic behaviors. Clones have low health and tend to do little damage. For example, a mesmer equipped with a sword has two clone-summoning skills: Leap, which launches him forward, leaving a clone at his location, and Illusionary Leap, which summons a clone at his location that then jumps forward.
- Phantasmsâ€”Phantasms are illusions that look like the caster but have their own names and carry special illusionary weapons, which look different and have specific behavior. Phantasms are more powerful, having more health and causing more damage. For example, a staff mesmer can summon an illusionary mage that attacks its target and deals extra damage for each inflicted condition.
Mantrasâ€”Mantras are a category of skill that have two phases. The mesmer first activates the mantra, which has a long cast time and replaces that skill slot with an instant-casting skill that the mesmer can then use. Mantras are powerful because many can be charged up before battle and then used in the middle of another spell, without interrupting that spell. For example, Mantra of Pain can charge up into an instant-damage power spike that can be used during a channeled spell, such as the greatsword skill.
