Made to scare the sh*t out of new players (fewer by the day sadly) and whip their rear. By invading you're able to invade people at soul level 15 and higher, meaning that you souls get some nice action. Try to get a friend to help you move the black knight gear through red summon signs or if you're a hardcore pve pro run through the entire game.
If you have any opinions or don't like this build, please share them as I'd love some feedback.
Happy hunting :)
