1. How do I proc combat animations more often?

2. Is there a way to become Vampire Lord after completing Dawn Guard Quest? It's interesting but at the same time annoying to have side effects yet I don't want to entirely throw it away.

3. Which enchantments gives you the most gold for use? I know sneak and absorb health gives a lot.

4. In smithing, what is required for new gear in either dlc?
