Summoners are trolls that utilise both Magic and Summoning in the Troll Invasion event. They are considered a high priority, as magic is generally something players fighting trolls often show little defensive interest towards, and can deal some damage. However, against black dragonhide armour or Void Knight equipment, their magic attacks would hit next to nothing. They are also able to use Summoning to summon a Thorny snail, Spirit scorpion, Bunyip or Granite lobster of various levels to assist them with melee combat, although they mostly summon lobsters. Their familiars are also considered monsters and thus must be killed off before going on to the next wave. Even when a summoner troll is defeated, the familiar will stay and continue to attack players.
