Arright so it is a very simple process.
1) Go to ::shops and buy 500 of each.
2) Tele to corp, stand near the skeleton lying around, around the banker, and far cast corp!
It wont know its health unless you get close, but just be paitent, and it should die. If you get lucky, you could even get a Sigil! So, yes, just remember to autocast!
