Magic

Alteration, one of the five schools of magic in Skyrim, affects the world around it by altering the laws of reality and manipulating it to one's own accord. Increasing this skill reduces magicka cost when casting Alteration spells. Historical information about the School of Alteration is provided in the lore article. The Alteration skill tree has a total of 10 perks, requiring a total of 14 perk points to fill.

In-game Description: The School of Alteration involves the manipulation of the physical world and its natural properties. This skill makes it easier to cast spells like Waterbreathing, magical protection, and Paralysis.

[edit] Summary

Alteration contains a range of defensive and utility effects.

In some ways the protective spells in Alteration are an alternative to the Wards found in the school of Restoration.

[edit] Spell List Notes

  • The base cost for spells is the amount of magicka that would be necessary to cast the spell at 0 skill without any perks. The magicka cost at 100 skill is 41% less than the base cost; the cost can also be reduced via enchanted apparel and by unlocking various perks. See Spell Cost for the full magicka cost equation.
  • Skill level indicates which skill perk needs to be unlocked to decrease the spell's magicka cost. "N/A" is used for special spells whose cost is not affected by any perks.
  • The "Where to Get" column only lists guaranteed locations for obtaining the spell tomes. Most spell tomes are also available in random loot; see Spell Tome Locations for details.
  • For higher-level spell tomes to become available for purchase, your skill in the school must be high enough. Also, master-level spell tomes can only be acquired once that school's ritual spell quest has been completed.
  • All spell tomes have a weight of 1.
  • Skill XP can be modified by scripts and by the game engine itself under various circumstances. The exact XP you receive may vary from the numbers listed here.
  • Magicka cost and skill XP are rounded down, both in game and on this page. Because of this, you may find that you cannot cast a spell even though it appears you have exactly enough magicka to do so.

[edit] Mage Armor and Exceptions

Wearing any piece of apparel with the keyword ArmorLight or ArmorHeavy, including equipping such an item after a Mage Armor spell has been cast, will completely negate the armor bonus from any Mage Armor perks. However, shields do not use either of these keywords, so equipping a shield will have no effect on the bonus. There is also a small assortment of apparel items that have an armor rating but lack the relevant keywords and thus can be worn without disabling the Mage Armor effect:

[edit] Magical Effects

A list of standard alteration spells can be found on the Alteration spells page. The following individual effects are all considered to be part of the school of Alteration (see the individual effect pages for full details on availability; the Magical Effects article also provides a summary):

[edit] Skill Increases

[edit] Character Creation

The following races have an initial skill bonus to Alteration:

[edit] Trainers

[edit] Skill Books

[edit] Free Skill Boosts

[edit] Gaining Skill XP

  • Casting higher level spells gives generally faster skill increases (Novice<Apprentice<Adept<Expert<Master).
  • Regenerate Magicka effects help reduce downtimes while training.
  • It is possible to reduce or even completely eliminate the magicka cost of spells by stacking Fortify Alteration enchanting effects, which is very helpful for Alteration training. The Secret of ArcanaDB power does the same thing, but only for 30 seconds.

[edit] Casting with Enemies Nearby

Repeatedly casting high-duration Alteration spells (like Oak Flesh, Stone Flesh, Iron Flesh, or Ebony Flesh) while in a combat situation will quickly increase one's Alteration skill. An effective method for doing so very quickly:

  1. Get a melee based follower and/or conjured melee atronach (Familiar, Frost Atronach, Ash Spawn, or Dremora Lord) to attack an enemy or group of enemies. The player can usually cast their alteration spell from safety during combat while the follower and/or conjured pet do actual fighting. This allows for leveling and questing at the same time. Casting a flesh spell in one hand and Bound Sword in the other will level both Alteration and Conjuration at the same time.
  2. Find a place with an enemy or enemies that only use melee attacks that also has a high platform or place otherwise out of reach of the enemies. Preferably, kill all but one of the enemies: Bleakwind Basin works very well for this purpose. Alternatively, along the shore of the Sea of Ghosts, the Horkers can be made aggressive without them actually attacking, allowing one to move far enough away to use the Wait function but still close enough to train the skill. And then there's Roadside Ruins, where a Spriggan Matron will notice the player, but she cannot attack since she's trapped inside. Slaughterfish can also be exploited by getting their attention and then standing on a nearby shore to cast.
  3. With both hands, continually cast the highest level Alteration armor spell. Casting the higher-level spells progresses the skill faster (Oak < Stone < Iron < Ebony), so it might be advisable to take a break part way through to go buy them once you've reached a level where the better spells are available. Often the enemy will run far enough away from your location to allow you to use the Wait function. If so, wait an hour to get more Magicka to keep casting the spell, or just wait until it refills itself. The giants in Bleakwind Basin will almost assuredly run away, though, if you're standing on the rectangular pillar near their fire. Mammoths never run away from you when they can't reach you. Using this method, one can go from 0 Alteration to 100 Alteration in roughly 40 minutes, but it depends on total Magicka available, particular spells cast, and the location chosen.
  4. Use a follower or permanent summon to continuously attack an NPC that cannot be killed. If your ally can keep the NPC on their knees, this leaves you free to repeatedly cast a spell.
  5. Once the Quiet Casting perk from the Illusion school of magic and the Throw Voice shout from Shearpoint have been acquired, one can misdirect enemies to and fro, and cast any of the "...-flesh" spells while they are searching for you. Using a magicka regeneration potion is useful in this scenario. An extra added benefit is that you can constantly sneak around enemies while casting, increasing your Sneak skill as well.

[edit] Magelight

Magelight can be cast anywhere for a small amount of XP, such as while walking to some distant destination, making this a sure but slow way to level Alteration.

[edit] Water Breathing Trick

After you learn Water Breathing, another way to quickly level Alteration is to stand in water and repeatedly cast Water Breathing. You don't actually have to be underwater, just standing in it (this only applies to pools of water you could actually dive into; so the small streams in Whiterun won't work, but the river outside will as will the pool just outside the entrance to Dragonsreach).

[edit] Casting Detect Life Spell in Cities

The Detect Life spell increases your Alteration experience depending on the number of targets it is currently detecting. Using it on your horse in the wilderness is almost useless, while using it in crowded location (the market in Riften during the day, for instance) gives incredible training speed. The more living objects in range, the better.

Solitude - 8:00am until 5:00pm: from the west entrance, follow the road leading to the Blue Palace. Just a little bit after you go under the bridge is a small "cliff side" on your left. If you stand there wearing 100% Alteration Magicka reduction equipment or use the Secret of Arcana power, two-handed casting of Detect Life for about 10-15 minutes should get you to 100 Alteration.

In the downstairs area of the Blue Palace (assuming the player has completed the Stormcloaks questline) you can level Alteration from 15-100 in approximately 14.5 minutes by constantly single casting Detect Life with The Mage Stone active (magical skills level 20% faster.) The great thing about this spot is that the NPCs are always there and never leave the area, allowing you to constantly gain levels without having to wait for NPCs to return the following day. Dual Casting does not provide an experience boost in this case, so single casting is all that is needed.

[edit] Casting Telekinesis

Holding any object in the air with Telekinesis without picking it up also gives a very high amount of experience. If the suspended object touches any NPC they will become hostile though, so be careful. If you can get a total of 100% magicka reduction cost, and fast travel while holding an object, the game will act as if you had kept casting for the whole duration of the travel, and level Alteration appropriately. For example, fast traveling between Riften and Markarth will increase your Alteration skill to 100, even if you start from 15.

[edit] Transmuting Ore

Outside combat, you can gain a substantial amount of Alteration experience if you know the Transmute spell by using it to transmute iron ore into silver and gold ore. Even at low levels of Alteration, it should be possible to cast Transmute (an Adept level spell), although if you have been busy mining it may take a long while to turn all of your iron into gold (which you can then smith into jewelry for Smithing experience). The Transmute spell is not available from spell merchants, but the spell book is in two fixed locations in dungeons.
