Summon Meteor: Ultimate Destruction

Now also available at the Skyrim Nexus: http://skyrim.nexusmods.com/downloads/file.php?id=12441

Update:
* Fixed Summoning/Magic Absorption bug, thanks to Nanayo on Skyrim Nexus for the fix!
* Added new spell, Meteor Rain.
* Reduced power of Meteor Shower and made it 1-handed.
* Added some subtle and not-so-subtle smoke and impact effects to Summon Meteor ('cause, you know, there weren't enough already!)
* Tweaked damage of Meteor Shower, Rain, and Storm spells.
* Increased speed of small meteors to improve the likelihood that the enemy will still be there when they hit ;)

Meteor shower: A low-Magicka spell that drops meteors on the target area. This spell drains 10 magicka per meteor, up to a maximum of 8.

Meteor rain: A low-Magicka spell that drops a number of meteors on the target area. This spell drains 10 magicka per meteor, up to a maximum of 20.

Meteor storm: DESTRUCTION RAINS FROM THE HEAVENS. Many, many meteors fall very rapidly over a wide area. This spell drains 10 magicka per meteor, up to a maximum of 100.

Summon Meteor: Drops a single, enormous meteor on the target area, vaporizing anyone unlucky enough to be standing under it and scattering everyone else to the four winds. The rock falls almost instantly and has a huge blast radius; don't be anywhere near it. This spell leaves a big rock at the impact site for a few seconds.

Drop it on bandit camps. Drop it on forts. Drop it in the courtyard of the Thalmor embassy :D Drop it on a dragon... if you're brave enough.

Find the spell tomes on Farengar's desk.

This spell can and WILL kill you. Cast it at a distance. It will not work indoors.

Known bugs:
* If your computer is near the bottom end of Skyrim's hardware requirements, these spells are glitchy and will take a long time to finish casting. They rely on fast script processing, so I'm not sure this can really be "fixed". Shouldn't be a problem if you can run with Medium settings or higher.

Technical details:
* Meteor Shower/Rain/Storm alternate between the Fireball and FireboltStorm spells. Each deals about the damage you'd expect from a Fireball spell. FireboltStorm spawns small rocks and has a knockback blast radius of 30.
* Summon Meteor deals 500 damage w/disintegration to an area of 30, then deals Firestorm-like damage to everything up to 150 units away. About eight direct hits from this will kill an Elder Dragon in Master difficulty, though it's pretty hard to actually hit them directly with it.
* These spells do not apply the Intense Flames perk. Well, actually they do, but since this spell works using a remote actor, they're afraid of it instead of the player, and it's too far away to run from.
