Hagrid is obviously gifted with magical creatures, but do we know if he has any other particular magical talents, taking into consideration that he only completed three years at Hogwarts? I think that Hagrid demonstrates with his pink umbrella/broken wand that he's basically competent at rudimentary charms. Perhaps his knowledge of the Forbidden Forest would lend his skill to potions or herbology?
What else was Hagrid skilled in besides Care of Magical Creatures?
