CNJ using THM spells.

[Velox]

You can't always trust the examine function as sometimes it fails to update properly. You can always look at the weapon though. CNJ staves and wands are made of wood, while THM are metal and jewel.

If it truly was a CNJ casting THM skills, then this could be a major hack. I highly doubt it though, it was probably mistaken identity.

She was definitely a CNJ. She wielded a wand.
