So when during the siege on 12/13/2015 Incendiary vs lncendiary i found out that you can attack your own lodestone. You ask how i do it? Well its easy all you do is summon your own mortar and "purple up" aka activate bloodlust mode then start firing away on the the lodestone and you do damage. Don't believe me watch the youtube videos and yes i do have damage chat log activated and yes i do have in settings et to show only my own attacks. you want my pc specs, i doubt it has anything to do with that, just a flaw or maybe it was intended part of the mechanics
