The spells can be only be found inside a special dungeon (vanilla dungeon) in Skyrim. I will include a cheat that will tell you where to find the spells and I will also post a video that spoils the location. However I can give you a clue to where to find them. They are located within a vanilla necromancer dungeon.

Note that these spells are considered death magic, and they cannot be resisted. They also have custom sound effects and I will be adding more spells for sure. Send me a message or post a comment if you have anything necromancy related and I will try to add that to this mod.

The two spells that are included are: Death Ray, this spell is sort of a skill shot spell with a really high amount of damage. 500 death magic damage to be precise, the mana cost is very high so you won't be able to use it a lot. But as you progress in your conjuration skill the mana cost of the spell will decrease of course, but it still won't be a spell that you can use over and over. More likely once per battle.

The other spell is called: Implosion, it deals a massive AoE damage to any target around you and (100 death magic damage.)

If you have any problems or errors, just send me a pm and I will try to help you!
