Summoners have a high offensive power at lower levels but at level 55+

Vicious Summoners specialize in, as their name suggests, summoning NPC Aika Gold creatures to aid their owner. Summoned creatures are either "Beasts" or "Libido" types; Beasts specialize in elemental damage, while Libido is demonic forms specializing in poison and curse.

In addition to having summoned creatures, Summoners wield either twin swords or staffs. They can dispatch summoned creatures to fight other monsters, which give the player experience without directly engaging in combat, the use of this practice is discouraged in PvP combat, because of its questionable nature although it does little damage at higher levels.

However, Summoner lack the natural defence that most other classes have, and they are short on skills, both offensive and defensive, all due to their ability to summon. Most Summoners believe that because of this, using their pet in PvP is fair, just as using Sword Defence as an Azure, healing yourself as a Segnale, buffing as a Bagi, etc.

Summoners have a high offensive power at lower levels but at level 55+ they become worst pvp class due to low defense and shield by proxy along with lowered attack as level increases, unable to cope with the increased defense of the other classes, until they hit the higher levels when their best weapons and armour are unlocked to them and their high "cosmos skill's".
