In Aion the cleric is the main support and is certainly a essential for many scope of the game (aion gold). The cleric is the only level that can actively disperse both physical and mental debuffs and is the main level (cheap aion kinah) for single target and AoE healing capabilities. Their long list of healing skills covers practically all of the different types of recovery spells one could hope for, includeing: high powered single target heals, wide range group heals, single and multi-target debuff removal, shielding spells, healing over time spells which increase primary resistances, and resurrection spells.
Gather all of these capacility to make the cleric a must in any kind of PVE or PVP scenariy. Also clerics are armored with chain armor which when coupled with their healing ability, make the cleric a solid, almost impassable target. When it comes to weapons, clerics are proficient in wielding maces and staves. Most clerics often can found wielding a mace and shield combination as this increases the survivability of the level by giving them a chance to block incoming physical strikes. Some clerics may opt to use a staff for the slightly greater magic boost and physical attack it comes with. However, a staff wielding cleric is a rarity in PvE situations and is almost never seen in any sort of PvP position.
