Wizard subclass
Transmutation
Minor alchemy, a transmuter’s stone, and transformative mastery.
Transmutation starts by changing the normal Wizard play pattern through Transmutation Savant; Minor Alchemy, giving the subclass its first clear mechanical identity.
Later features such as Transmuter’s Stone, Shapechanger, Master Transmuter expand that identity at higher levels, so the subclass has a clearer role in combat, exploration, utility, or support.
