Igneous Summoning Stone
Posted December 10, 2009on:
The Igneous Summoning Stone summons an imp, who knew?
I wasn’t sure what it was and if it was use once.
The Igneous Summoning Stone can be double-clicked to summon a Fire Imp ally of your level that lasts for 60 minutes or until slain in combat. It can be activated once every 60 minutes per character, and only one summoned ally from a summoning stone can be present in an instance at any one time. This item has unlimited uses, cannot be used by level 20 characters, and can only be used in explorable areas.
Here is a picture of the imp.
The different summoning stones can be found on the guild wars wiki.
