Fromsoft thought it was an absolutely genius idea to add an npc to Eleum Loyce called Maldron the Assassin that acts exactly like a human player that decides to backstab you with a lance, ultimately killing you in a single hit because lances are absolutely broken in pvp. They also decided it was a good idea to make it non-hostile except for when you turn your back to it, making you prone to a backstab. I have lost 200,000 souls due to this npc. Best souls game ever
