Priest

' "The Priest' is arguably the backbone of any successful party. Their ability to keep Daeva battle-ready, even in the direst of circumstances, cannot be underestimated, and is absolutely vital in ensuring groups survive against the more pressing challenges in Atreia. Ailing comrades can be brought to full health in a heartbeat, and deadly poisons can be cured just before victims would be snatched away from their friends and family, all by the fair hand of a kind and benevolent Priest." --AION wikia''

Cleric
Considered the "natural" progression from Priest, these healers can sustain any group with their wide variety of heals, limited buffs, and dispels that can vanquish even the deadliest of poisons. While being able to provide a limited amount of magical attacks the Clerics main purpose is to keep their allies--and themselves--alive. They have better defense than Mages or Scouts, but can't compare to the Warriors.

Clerics can use the Staff or MacexShield combo. MacexShield is the most common and used for blocking incoming attacks while a Staff can be used for soloing, magical damage and physical damage purposes.

Heals of the Cleric comes in all shapes and kinds. Heals over time, sudden heals, group heals, and buff heals. They may not be versatile in weapons but have enough healing methods to keep any party and class alive. They also have a number of resurrection skills to aid fallen party members on the spot.

Chanter
Chanters have the ability to raise the skills and abilities of their allies through the means of Mantras. They have a number of heals like their Cleric counterparts, but their buffing rises above any Priest. Their defensive is the same as the Clerics, which can be even better if they make use of their defensive buffs.

Like a Cleric, chanters can use a Staff or MacexShield. Because Chanters are more likely to DPS than Clerics, who sometimes don't even fight at all in a group setting, they use Staves to raise their Magic Boost and Physical Attacking capabilities. MacexShield may come in as a secondary but are rarely seen unless they have to play main healer.

Mantras are the staple of any good Chanter. They have a number of them, each possessing different boosting abilities that can go beyond just buffing the basic stats. Some Mantras even have the ability to raise healing and mana regeneration, speed, and critical capabilities. Sometimes Mantras will come with more than one benefit. A downfall is that only 3 Mantras may be activated at a time.
