Some classes in Lineage II have the ability to summon a servitor. In order to summon a servitor, a particular number and type of crystals are required. Servitors exhibit excellent abilities both as a player's partner during combat and also as a highly skilled and expert hunter.

Servitors come in two types — the controlled servitor type (pictured right) and the uncontrolled servitor type (pictured left).

The controlled servitor type is useful in the sense that a summoner can directly control its actions for strategic purposes during combat. However, the disadvantage of this type is the fact that the controlled type servitor can only be summoned one at a time.

The uncontrolled servitor type is not controlled directly by the summoner. However, the advantage this type of servitor gives to a gamer is that two or more uncontrolled servitors can be summoned at the same time.

Cubics fall into the uncontrolled servitor category. Controlled servitors can only be summoned by particular classes. It is through skill acquisition that these classes are able to conjure up their servitor companions. The three main classes in the summoner category are Warlock/Arcana Lord, Elemental Summoner/Elemental Master and Phantom Summoner/Spectral Master. However, there are a few exceptions that will be detailed on the next page.

All servitors that appear in Lineage II consume crystals. Each time one level of an applicable summon skill is mastered, the number of crystals required to summon a servitor will change.

The total amount of crystals required for summoning varies from servitor to servitor. But with all servitors, there will be an initial crystal consumption for summoning, followed by a periodic consumption over set intervals. The details surrounding this will be outlined when you mouse over the icon in your Active Skills list.
