All elementals appear to have been removed from the game, as of the last patch. The only Elementals to date that have been found have been the Elemental Warriors, Elemental Crusaders, and Elemental Monstrosities -- **NO** other elementals exist below the castle. (Imps, though, do still exist in rare spots.)
All of the info I included with the submission has not yet been posted here so I will elaborate a bit.
This mob always drops the Lore of the Elementalist and the Scroll of the Conjurer rolled up scrolls. What quest these items is used for I have yet to discover but I do know that as of yet asking anyone in paineel or in euradin about them will gather no response. This mob is NOT summoned only his pet is so Vs summoned spells will not work as it will with other non golem/undead/rat mobs in the hole. This mob is a magician in class and summons an earth pet after spawning. He can spawn in the hole anywhere that an elemental channeler can spawn. He does have a lot of life as most named elementals in the hole do but this one nukes harder than the wizards or visier's. I will post more as I learn it if no one else has but this is all I have currently. Though I must say /bonk illia for not using my picture with name and guild credit on it =P.

Me and my guild Wrath of Wrecking, got done raiding The Hole, and while we were there we came to this mob, he was easy to kill but when we killed him it droped 2 things, Scroll of the Conjuar and Lore of the Elementalist. Scroll of the Conjuar was Lore, Magic, No Drop. While the Lore of the Elementalist was onley No Drop. Does anyone know what this iteams are for?
