How can I kill Ancano if I am a level 13 vampire?

Vampires don't exist, so he/she is definitely lying. Remind them that vampires can't go outside in sunlight, can fly, drink blood, etc. Ask him/her to prove that they're a vampire....

Dish soap kills bugs by melting the waxy coating on their exoskeletons. This means all bugs with exoskeletons will die if you use dish soap, not just chinch bugs.

No, the laser level is generally going to be much more accurate and helpful. A spirit level is fine, but it's not what professionals use anymore.

You can't, because when you attack him he will defend himself. He is also marked as immortal beforehand.

When you are a werewolf you are resistant to all diseases, but with the Dawnguard DLC you have the option to become a vampire, however you won't be a werewolf...

Both are equally cool but if you commit crimes as a werewolf, you won't be punished as a human.

Nope. Sims appear to have infinite plasma/blood which could be so that vampires have an easy way to replenish the thirst need or so that Sims couldn't accidentally be killed.

I would avoid taking extra supplements if your levels are in the normal range.

Beeswax would affect the hold of the pomade, and oil affects the shine.

Priests can only equip Maces and Daggers as weapons. Dagger is the preferred weapon, as it is usually famed for its high dps.
