Apocalypse - Magic of Skyrim 9.45

Vanilla Skyrim has a variety of issues. Most would agree that the passage of time has not been kind to it, with a ton of people rightfully pointing out a ton of issues with it. Luckily, Skyrim has one of the largest modding scenes around and a ton of creators have dedicated themselves to fixing the game's many issues. One of them is Apocalypse - Magic of Skyrim, a mod that gives you alternate starts for your adventures in Skyrim.

To install Apocalypse - Magic of Skyrim, drag it into the Skyrim Data folder, as well as using LOOT to determine the optimal load order so you don't crash your game constantly, much like most Skyrim mods. 

This mod adds a ton of different custom magic to Skyrim to really reward players who go deep into spells. The list of magic is far too long for us to cover it all, but some of the endgame spells are truly a sight to behold. There's Tornado, which summons a tornado at the target location and deals a ton of damage to your enemy. Another spell like it is Volcano, which does exactly what it sounds like.

Yet another one is Spectral Warband, which will clone all the allies fighting with you in battle, which can get crazy if you take other mods that let you have a ton of companions following you around.

All in all, Apocalypse - Magic of Skyrim is fantastic. Even if you aren't playing a mage character, the basic level spells are still incredibly useful.
