You want something like
self.assertRaises(AttributeError, lambda: self.combat.value = 1)
Or, combining the two responses and avoiding the lambda:
self.assertRaises(AttributeError, setattr, self.combat, 'value', 1)
Hmm... this might be a case where the lambda form is actually the more readable one...
