I'm on PSN, so the likely hood of hacking is slim, but the only other possible explanation for what happened to me was an OP Avelyn. I was dragon dueling and this cheeky laurel leaf trolly lookin mage summoned me. I spawn in, he's just standing there with Oolacile branch in hand and "nothing" in the other. Next thing I know "pew, pew, pewh!" YOU DIED I have 1520 HP, and I swear I didn't see his empty hand rise, as if firing a hidden Avelyn, but that has to be it. Only thing is, I didn't think an Avelyn could dish 1500+ in damage...I was full dragon body and the hit came as I was using the dragon body stone, so maybe counter damage...?
