So I was playing Dark Souls 2 today in NG++ and I got to the first dragonrider boss, so to make a fast fight faster I summoned two white phantoms. Everythin went great we killed him no problem, but then something happened that I have never seen before. I was giving the phantoms a goodbye bow when out of no where one of them cast some kind of hex and it killed me on the spot! I didn't know that whit phanoms could kill there hosts like that. So... help? Anyone have an answer to what happened?
