Demon's Souls - Trolling with Scraping Spear

So I spent last night invading 100 or so worlds just to troll with my Scraping spear, just had nothing better to do. Sorry for ruining your equipment fellas ;P
Soul lvl 12
Scraping Spear
Adjudicators Shield +5
Regenerators Ring
Fluted Armors set
Gives me 10hp per second and a lot of armor for that lvl. After landing 10 or so hits(doesn't matter if they block) thier armor and weapon is broken, doesn't matter what they do they can't kill me with that hp regeneration.
