Alter self

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

Effects
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.

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&mdash;height, weight, hair and skin color, gender&mdash;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 generally got longer durations.

The next version of the spell allowed a human-sized creature 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, and taking the form of a troll did not grant the ability to regenerate, for example. The creature's appearance (hair/skin/feather/fur color and texture, height, weight, gender) 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.

Sundering spell system
Using this spell the caster had three choices:
 * Aquatic form: gaining a more fit form for water environments like webbed fingers and underwater breathing.
 * Change Appearance: the caster would change form in any manner from number of legs or skin colour, length or what race the caster looks like.
 * Natural Weapons: Caster chose to grow natural weapons like claw, horns or fangs.

Effects
The effects will last for as long as concentration is held or a full hour has passed.
