Alter self, originally known as Quantoul's alterer,[1] was a transmutation or alteration spell that allowed the caster to change his or her body to a new form.[4][9][10][16]


This spell only worked on the caster, and transformations were limited to the same general body type, i.e., a biped could not become a quadruped or an arachnid.[4][9][10][16]

The earliest version of alter self allowed the caster to increase or decrease body size by half their normal size. All aspects of appearance, including clothing and belongings on his or her person, could be changed within that limit—height, weight, hair and skin color, gender—essentially anything that change self could do except that it was a real transmutation and not an illusion. If the new form had gills like a sea elf, the caster could breathe under water. If the new form had wings like a harpy, the caster could fly, although slower and more awkwardly than a real harpy. Other than this, alter self did not grant any special abilities: taking the form of a drow did not give the caster darkvision; having the head of a cobra did not allow the caster to spit venom; changing a hat into an iron helm did not improve the chances of avoiding head trauma. This version of the spell lasted several minutes but the exact duration was impossible to predict. More experienced casters got longer durations on average.[9][10]

The next version of the spell allowed a human-sized being to take the form of a creature as large as an ogre or as small as a gnome, but the type of creature had to be the same as the caster's type (e.g., humanoid or magical beast). This version did grant physical-related abilities as the form dictated, such as racial skills, natural armor, natural weapon skill, swimming, flying, or burrowing. It did not grant extraordinary abilities like darkvision or venom, nor did taking the form of a troll grant the ability to regenerate, for example. The creature's appearance (hair/skin/feather/fur color and texture, height, weight) had to be within the range of variability for a typical specimen of the creature chosen. If the new form could hold or wear particular equipment, weapons, clothing, or jewelry, then after the transformation those items were still being worn or carried. Otherwise, they fused with the new form and became nonfunctional until the spell ended. This version of the spell lasted at least a half hour and more experienced casters could extend this by 10 minutes per level. The spell could be canceled at any time the caster desired.[4]

After the Second Sundering, this spell had three variations to choose from:

Aquatic Adaptation
The caster's body transformed, adding gills and finger webbing to allow breathing and movement in underwater environments.
Change Appearance
The caster's general size and basic shape (e.g., bipedal) remained the same, but all other aspects of his or her appearance were changeable. No racial skills or new abilities were granted.
Natural Weapons
The caster could choose to sprout fangs, claws, horns, spines, pincers, or some other natural weapon, and gave him or her the skill to use it. The new feature was a magical weapon +1.

This version of the spell lasted while the caster maintained concentration, for up to one hour. During that time, the caster could choose a new variation at will. A wizard could duck into an alley and change appearance to resemble a barbarian, then jump in a river and use aquatic adaptation to swim away. While in combat, a change could be effected every six seconds but only movement and no attacks were possible while the change took place.[16]


Only verbal and somatic components were required to cast this spell.[4][9][10][16]


This spell was invented by the Netherese archmage Quantoul in –2028 DR (1831 NR, during Netheril's Golden Age).[17] It was a second level spell in the school of Variation.[18]
