By default only summonable is dremora lord, my mod adds 3 more dremora available for you to conjure.
1st Dremora Valkynaz, erroneously referred to as the Dremora Valynaz on occasion in-game, are a powerful form of Dremora equip with powerful daedric bow and arrows.
2nd his name on creation is dremora valynaz also known as dremora lord lol wish i can go back, and change it to enhanced dremoa lord instead but its ok.
3rd Dremora warlocks are members of the Destruction Mage NPC class and prefer to use spells in combat. They wear unique black robes and boots. In case they are forced into melee combat, they carry an iron dagger and a mace, sword, war axe, warhammer, greatsword, or battleaxe (any quality from iron to elven).
