Let say, for arguments sake, that a 10th level Wizard gains a Celestial Weasel Familiar. The HD of the creature with regard to effects pertaining to HD is that of the Wizard, i.e. 10. Would this imply that the familiar had the celestial abilities of a 10 HD celestial, or would the familiar still be treated as a simple weasel with only basic celesitial abilities (Smite Evil, etc.)
Thanks!
