The Bear summon granted by the Mug of Bear has a Bite ability which was very clearly not designed to be reused for anything but low-level wolves; the use description makes reference to "the feral wolf's teeth" and "barking," and the damage is calculated in such a way as to be significantly lower than expected for a level 7 summon.
Suggested course of action: change the Bite ability to have a generic use description and better damage scalability.
