Oblivion:Magical Effects

Oblivion: Magic

This page provides an overview of all the magical effects available in Oblivion. In most cases, these effects are used in a number of different ways - for example, to make spells, potions or poisons, or enchanted items. Certain magical effects may have limitations to their use; others may not be available to the player at all. More information concerning these and other details of magical effects can be found on the individual effect pages.

The following pages have information on specific ways of using magical effects:

  • Alchemy Effects: How to make custom potions and poisons with specific magical effects
  • Spell Effects: A list of magical effects used to create custom spells

Availability of EffectsEdit

The tables below list all magical effects available in Oblivion, sorted by magical school. The columns indicate:

  • Type: The purpose of this effect (although other applications are often possible: for example, see Cursed Enchantments).
    • Offensive: Used against opponents and generally considered to be hostile unless otherwise stated. In enchanting, typically used on weapons.
    • Defensive: Used for protective purposes and never considered to be hostile. In enchanting, typically used on armor and apparel.
    • Restorative: Used to undo damage. Restorative effects are never available as enchantments, although one or two items such as the Truncheon of Submission are pre-enchanted with such effects.
    • Other: Non-hostile magical effects which do not fit in any of the categories above.
  • Spell: Is this effect available from standard spells? (An asterisk in this column indicates that non-standard spells may be possible under some circumstances.)

General NotesEdit

Magnitude to Level ConversionEdit

Several magical effects are described in the game based upon the level of the NPC or creature that will be affected: Calm, Command Creature, Command Humanoid, Demoralize, Frenzy, and Turn Undead. (Rally is not.) Internally, each of these spells has a magnitude in points, used for example to determine the magicka cost of a spell. The equation used to convert from magnitude (in points) to the level of NPC or creature affected is fairly straightforward:

Level = Magnitude/4

The level is always rounded down. So, magnitude 3 yields level 0, magnitudes 4-7 yield level 1, magnitude 100 yields level 25, etc.

Spell effectiveness is applied to the spell's original magnitude; the actual NPC or creature levels affected by the spell are then calculated from the resulting reduced magnitude. Therefore, the levels shown for any spell are likely to be incorrect if your character is wearing armor. For example, Touch of Rage claims it works "up to level 18." However, if your character's Spell Effectiveness is 85%, the spell's actual magnitude will be 63.75 (75*0.85), resulting in a spell that only works up to level 15.

The maximum possible level of these spells, even at the Altar of Spellmaking, is 25. However, the maximum strength spell, despite claiming to only work "up to level 25," will in fact work on any level enemy — as long as your character has 100% spell effectiveness. For example, casting a level 25 Command Humanoid on an NPC of level 34 will succeed. This quirk prevents these spells from becoming effectively useless for high-level characters, who will only meet creatures and NPCs with levels higher than 25. If you are wearing any armor - even with armor skills at 100 - the maximum magnitude of a spell becomes 95 and therefore will only work on enemies up to level 23.

Options for HealingEdit

Multiple effects listed here provide various types of healing: Cure Disease, Cure Paralysis, Cure Poison, Dispel, Restore Attribute, Restore Fatigue, Restore Health, and Restore Magicka all help in recovering after combat. Which approach is necessary depends upon how you were injured (disease, spell, poison, weapon) and what your injuries are.

If you see a red value in your journal statistics and can't remember what caused that damage, the best place to check is on the Active Effects page on your journal. In most cases, you should find a corresponding entry that provides details on what is inducing the damage. If the details mention Poison, you need to use a Cure Poison effect; if the details mention Disease, you need to use a Cure Disease effect. If you do not see anything in your Active Effects page, chances are a Restore spell will do the trick.

The various Restore effects will heal magically-induced Damage as well as mundane types of damage (i.e., loss of Fatigue from a hard fight, loss of Magicka from casting spells, loss of Health from weapon or fall damage). Restore effects will not work on injuries due to Drain effects, nor (as noted above) will they work on injuries induced by disease or poison.

Dispel will work to undo Drain effects and other effects (both positive and negative), but only if caused by spells. Dispel will not work on injuries induced by diseases, poisons, or enchantments. In other words, a Drain effect that was induced by poison will not be undone by a Dispel spell or potion. Also, Dispel will not work on Drain effects from lesser powers (e.g., Spriggan's Curse that drains Luck).

Another option for healing is to visit any chapel altar (i.e., the chapels in cities or the wilderness chapels such as Weynon Priory or Gottlesfont Priory). At these altars, all negative effects will be healed, provided your Infamy is lower than your Fame; there is no need to determine what caused the damage or which specific spell is necessary to fix it. Wayshrines provide similar healing, although not quite as comprehensive. For evil characters, the Vile Lair official plug-in includes a Shrine of Sithis which provides similar effects, but only works if your Infamy is greater than your Fame.

Resistances and WeaknessesEdit

A large number of Resist and Weakness effects can be used to magically reduce or enhance a wide range of effects. The mechanics of each individual Resist/Weakness pair is the same. A Weakness is basically a negative resistance. Any creature's or character's total effective resistance is the sum of all active Resist and Weakness effects:

Total_Resistance_to_X = Resist_X - Weakness_to_X

Unfortunately, the character's Active Effects menu screen displays separate entries for resistances and weaknesses. Therefore, when interpreting the Active Effects menu, you need to be sure to check both the resistance and the weakness entries. All tables on this site (e.g., at Creature Resistances or Races) use the convention that a positive value in a "resistance" column is a resistance and a negative value is a weakness.

One implication is that immunities are not guaranteed. For example, all Vampires have a 100% Resist Disease effect and therefore are described as being immune to disease. Nevertheless, it is still possible for vampires to contract a disease if any Weakness to Disease effect is active - for example, if the Boots of the Swift Merchant are equipped, or if the Staff of Vulnerability was used. Similarly, Ghosts can be damaged (even killed) using Frost Damage spells, as long as a Weakness to Frost spell is cast first. The only absolutely impenetrable immunity is 100% Resist Magic, since any Weakness to Magic spell would have its magnitude reduced to zero, and there are no ingredients with a Weakness to Magic effect. Fortunately, magic-immune enemies are extremely rare, and the few that do exist are vulnerable to elemental damage poisons (no creature or NPC is immune to both magic and poison).

The various available resistances (and weaknesses) are:

  • Resist Disease: alters the chance of catching any disease.
  • Resist Fire: alters the damage done by any Fire Damage effect (from spells or poisons).
  • Resist Frost: alters the damage done by any Frost Damage effect (from spells or poisons).
  • Resist Magic: alters the magnitude of any spell effect (from a spell being cast, or from an enchantment on a weapon or staff). Certain types of poison effects are also altered: Damage Health, Damage Magicka, Damage Fatigue, Damage Attribute, Drain Health, Drain Magicka, Drain Fatigue, Drain Attribute, and Burden poisons ARE resisted by Resist Magic. Paralysis and Elemental damage (Fire, Frost, and Shock Damage) poisons ARE NOT resisted by Resist Magic. In other words, all spells are resisted by Resist Magic, and all poisons except for Paralysis and Fire/Frost/Shock Damage are resisted by Resist Magic, but since NPCs don't use Fire/Frost/Shock poisons, players don't have to worry about them.
  • Resist Normal Weapons: alters the damage done by normal weapons (i.e., non-enchanted weapons except for bows, silver, Daedric, and a few other rare weapon types).
  • Resist Paralysis: alters the chance of being paralyzed (from spells or poisons; power attacks with a chance to paralyze are not affected by Resist Paralysis).
  • Resist Poison: alters the magnitude of any effect delivered by a poison, including poisons such as Fire Damage.
  • Resist Shock: alters the damage done by any Shock Damage effect (from spells or poisons).

Whenever resistances of different types combine, their effects are multiplied. For example, a Fire Damage spell is affected by both Resist Fire and Resist Magic. The total damage done by the spell would be multiplied by:

(100 - Total_Resistance_to_Fire)/100 * (100 - Total_Resistance_to_Magic)/100

Drain vs. Damage vs. AbsorbEdit

Each of these effects reduces the points of a target's statistic. Health is most commonly affected, but Fatigue, Magicka, Attributes, and Skills can also be affected. These effects differ in various ways:

  • The spell school that governs the effect.
  • Whether the spell affects the target only, or both the target and the caster.
  • Whether the damage instantly reverses at the end of the spell's duration, or healing is necessary to repair the damage. (The latter type is also cumulative; i.e., if the effect duration is more than one second, additional damage is dealt - at the listed magnitude - each additional second of duration.)
  • The availability of the effect as a standard spell, and therefore how easy it is to create custom spells with the effect.
  • The relative cost of casting the spell.
  • The availability of the effect as a poison.
Drain
  • All Drain effects are part of the Destruction school.
  • Drain only affects the target.
  • Drain effects last for the duration of the spell; they are then automatically reversed. (To reverse the Drain effect of a spell more quickly, use Dispel.)
  • Drain Fatigue and Drain Health are available as standard Novice Destruction spells. Drain Magicka and Drain Skill are available as standard Apprentice Destruction spells. Drain Attribute is not available as a standard spell, but can be obtained for custom spells, as detailed on the effect page.
  • Drain is the cheapest effect for the amount of power delivered; i.e., it will cost less gold to obtain and Magicka to cast than Damage and Absorb at the same magnitude.
  • There are built-in poisons with Drain effects for Health, Magicka, Fatigue, and all eight standard attributes, but Drain is generally not available for custom poisons. One notable exception is that a master alchemist may make a Drain Health poison with a Nirnroot. The other exception is the new ingredient Unrefined Greenmote - added by Shivering Isles - which has Drain Health and Drain Fatigue effects, allowing poisons to be made with these effects by combining with Nirnroot.
Damage
  • All Damage effects are part of the Destruction school.
  • Damage only affects the target.
  • Damage effects will accumulate over their duration, unlike Drain effects. For example, Damage Health 5 pts for 10 seconds will result in 50 total Health points lost (assuming 100% Spell Effectiveness). The points lost to Damage remain lost indefinitely, until reversed with the appropriate Restore effect (including general healing options such as a blessing at an altar). Fatigue is automatically and continuously regenerated over time by all characters, and Magicka by all characters without the Atronach birthsign, but there is no instantaneous reversal of the effect at the end of the duration, unlike with Drain effects.
  • Damage Fatigue and Damage Health are available as standard Novice Destruction spells. Damage Magicka is available as a standard Apprentice Destruction spell. Damage Attribute exists as an effect (e.g., for poisons) but cannot be found as a spell. Damage Skill does not exist in any form.
  • Damage is more expensive than Drain for derived attributes (Health, Magicka, and Fatigue); i.e., it will cost more gold to obtain and Magicka to cast than a Drain of the same magnitude. It is the most expensive of the three (among Drain, Damage, and Absorb) for the eight standard attributes.
  • Damage is available as a standard or character-created poison ("potion magic effect") for Health, Magicka, Fatigue, and all eight standard attributes.
Absorb
  • All Absorb effects are part of the Restoration school.
  • Absorb affects both the target and the caster, and can only be cast on touch.
  • Absorb effects transfer points of the given statistic from the target to the caster, simultaneously damaging/draining the target's statistics and restoring/fortifying the caster's. With respect to instantaneous reversal and regeneration, the effects of Absorb vary depending on what statistic was targeted:
  • All Absorb effects are available as standard Novice Restoration spells, and therefore Absorb is the easiest effect to acquire for creating custom spells.
  • Absorb is slightly more expensive than Drain for the eight standard attributes; i.e., it will cost more gold to obtain and Magicka to cast than a Drain of the same magnitude. It is the most expensive of the three (among Drain, Damage, and Absorb) for derived attributes (Health, Magicka, and Fatigue).
  • Absorb is not available for any poisons.
Additional Information
  • The description of Drain in the official game guide uses the misleadingly equivocal phrase "The magnitude is the units reduced each second of duration", which can be inferred either as meaning that units are reduced cumulatively over the period of duration (which is incorrect), or that they are reduced by no more than the total magnitude over the period of duration (which is correct). The definitions in the above sections are correct.

Restore vs. Fortify vs. AbsorbEdit

Each of these spells increases the value of a statistic - such as Health, Fatigue, Magicka, attributes, and skills. Restore increases statistics back to their usual values (i.e., healing earlier damage) as a permanent increase (at least, until you get injured again!). Fortify increases statistics past their usual values, but only for a limited period of time.

Restore will not always repair damaged statistics, even if they are shown in red in your journal: specifically, it will not repair decreases due to Drain effects (use Dispel for spell-based effects or Cure Poison for poison-based effects instead), nor will it repair decreases caused by Diseases (use Cure Disease instead).

Absorb transfers points of a statistic from the target to the spellcaster. The effect upon the spellcaster varies. For Absorb Health, Absorb Magicka, and Absorb Fatigue, the effect is the same as a Restore spell; i.e., values are healed up to their base value. For Absorb Attribute and Absorb Skill, the effect is the same as a Fortify spell; i.e., the values are temporarily increased past their base values.

Reflect Spell vs. Spell Absorption vs. Resist MagicEdit

All of these spell effects help prevent enemy magic from harming you.

Reflect Spell attempts to bounce harmful effects back: its magnitude is the percentage chance that it will succeed, and if it does, all of the effect is applied to the caster of the incoming spell instead of to the target.

Spell Absorption attempts to convert incoming magic into magicka for the target: its magnitude is the percentage chance that it will succeed, and if it does, all of the incoming effect is negated, and the target with the Absorb effect active receives magicka proportional to the magnitude of the incoming spell.

Resist Magic always works, and reduces the effectiveness of the incoming spell by a certain percentage.

If two or more effects are active, there can be interesting consequences. Reflect Spell will always be counted above the other two, so those with the Atronach birthsign will have to be especially cautious using this.

Spell Absorption is counted after Reflect Spell; if you have less than 100% Reflect and it fails, Spell Absorption kicks in. Spell Absorption still trumps Resist Magic, however, so if you have no Resistances or 100% Resistances, it won't matter.

Resist Magic is taken into account last.

BugsEdit

  • Sometimes the active effects list could be erased completely just leaving the armor and clothing enchantments as active, and missing all racial and quest obtained effects. This has been seen to happen when lockpicking a loading screen door while getting the skill increase message. When this happens, try saving in front of the door, then pick the lock to receive the skill increase message, exit the lockpicking screen, and try again. This effectively stops the bug from happening. ?
