Ways to change your creature type? (or add type)

[Crimeo]

I'm looking for as many of these as possible. From anything to anything.

I'm just filling out a bunch of NPCs in a campaign with this sort of a theme to it of heavy transmutation shenanigans, but I'd like to stay within written rules as much as possible.

The lower the level it is possible, the better.

[Just a Guess]

Adding a type:
- Racial heritage feat for humans (or outsiders who count as human)
- Contracting Lycanthropy adds the shapechanger type

Becoming fiendish: (Not sure whether that changes or adds to the type as well)
- A child sired or born by someone with the Lamashtu's mark feat adds fiendish template.
- A child born by a follower of Lamashtu who was wearing a Demon Mother's Mask while being impregnated by an animal gets the fiendish template. A male follower impregnating an animal results in a fiendish animal.

Changing type:
- Infesting a dead body with certain fungus spores turns it into a Fungal creature
- having 4 damnation feats changes the type to outsider (native)

becoming a lycanthrope, vampire, lich, zombie, skeleton, demon posessed creature or mutant

Or getting any number of other acquired templates that I dont have time to list right now.

Life oracles have a revelation that gives them the elemental subtype. It's limited to rounds though.

The 4 damnation feats turn you I to an evil outsider ( native) once all are taken if I'm not mistaken.

Nature oracle capstone can change to animal or plant. I remember Anzyr once pointed out a way to get infinite HD with Awaken with this capstone.

If it was story/DM-induced just find a template you like and tack it on. For story-purposes some earlier event cursed/converted/gifted these NPCs said templates if there were some shenanigans going on.

Wizard please, you so crazy.
