More Skyrim fun:
Flaming Familiar is a fun and easy way to perform kills for the Dark Brotherhood. Simply stand next to your target (that isn't hostile toward you), cast FF (or in my case, double FF), and stand back as they howl and explode. It may take a few tries, but when they do kill your target, you don't get in trouble for it. In fact, I performed one kill directly in front of a guard, and he simply walked over to the body and asked, "Who did this?"
The only problem is repeated use of FF at close range does hurt you, and even Wards don't seem to protect you (unless I'm using them wrong).
