Transmutation

The transmutation school of magic consisted of spells that changed the physical properties of some creature, thing, or condition. The school was previously known as alteration. A wizard who specialized in transmutation is known as a transmuter.
Casters who study within the School of Transmutation are able to manipulate the physical properties of both items and people. This could be something simple – such as turning copper into gold.
It is among the most popular and useful of all of the schools, allowing a mage to manipulate time and space. Perhaps the most iconic Transmutation spell is Polymorph, which allows a mage to temporarily turn something—or someone—into something else.
Transmutation spells included bull's strength, eagle's splendor, and the various polymorph spells.
When a spell or effect rooted in a school of magic is unleashed, the weave takes on the characteristics and appearance of this magic, such as the characteristic orange glow of transmutation.
