Ooh, that could be fun. A wolf wizard with a Sight based around the superior canine senses like scent or hearing.
The name "Angua" pops up in my head right now ;DCertainly no reason you couldn't, just not necessarily a can of worms you want to open for an NPC. If a were did go full Practitioner though, Id be asking who taught them. Anything from fae to dragons to Native American wizards (like with Tera and LtW) would work, but getting past the one-trick-wonder level without a teacher/guide of some kind would be damn hard.
But jokes aside, why shouldn't a weresomething pick up other supernatural powers? I can totally see it, I might even be ok with a weresomething evolving into a focused practitioner and even a full blown wizard over time. The shapeshifting might just be his way of first manifesting his powers. I think someone somewhere suggested, that you could take powers for highly refined spells. Breath weapon for attack spells for example, or true shapeshifting for shapeshifting thaumaturgy. And following that logic, if you can upgrade from channeling and ritual to evocation and thaumaturgy, why not upgrade the even more specialised spell?
Based on going through a bunch of "Word of Jim" posts (someone on the spoiler board has collected practically every post that Jim has made on the Dresden file - and has sorted them by topic) I think I know the answer to this one.Cool that's the sort of information I was after...
A were's lifespan is whatever it has to be for Jim to write a kick ass story. And since all it takes is for Harry (or Bob) to say "these were spirit animals awaken, those were hit by a spell, that kind were played with by fairies, etc" Jim can make as many different types of weres as he needs to. If he thinks it would be cool to have a wolfwere with a human lifespan fall in love with one that has a wolf lifespan, then that's what is going to happen (a tragic, doomed loved in the Dresden Files? It fits).
