How to become a witch/warlock in The Sims 2 without cheats

A witch or a warlock, the male counterpart, is a life state introduced in The Sims 2: Apartment Life and reintroduced in The Sims 3: Supernatural. The Sims 4: Realm of Magic includes a similar version of this occult type called "spellcaster".

To become a witch in The Sims 2: Apartment Life, a Sim (teen, young adult, adult or elder) must be turned by one. This can be done by either befriending a High Witch (who at times show up at a community lot) and asking to be taught the ways of light/darkness, or directing a playable witch with enough magic skill to cast Magus Mutatio on the target Sim. Once done, the Sim will become either a good or evil witch, depending on the type of witch who turned them, and will have an extended name including their alignment tile (e.g, "Goneril Capp the Evil Witch"). They will also receive witch attire (robe and hat) and the required kit (cauldron and spellbook) to partake in magic. Their colors will be determined by the witch they were turned by.
