Summon

Summon is an ability, power, or spell that allows the transporting of a creature from another place (in game world, other dimension, etc.) to the caster.

Note

 * Pets of Hunters and Warlocks usually appear via summoning.
 * Warlocks have a useful spell called the Ritual of Summoning to transport other Player characters to the warlock, if the warlock has 2 more members present in a party to help with the ritual.
 * Two members of a group can use a Meeting Stone to summon additional members of the group (as of patch 2.0.1).
 * Shamans can summon a Fire Elemental Totem or Earth Elemental Totem to summon their respective Elementals.
