I'm so wigged out right now. I was summoned today to help a guy fight the dragon in the depths. He had summoned another person before me, so us two phantoms are to protect our summoner, right? Well, we got invaded by an assassin. He had double daggers I think. Problem is, I saw him, all three of us saw him, but then he would disapear completely. No outlining, no transparency. He was completely invisible. He would appear, then disapear, but I'm sure it wasn't lag because it was very fluid like and controlled (I think). He goes into the other room, we back out and move away. No sign of him, nothing, absolutely nothing. I leave to kill some rats thinking those two would be able to handle this guy (We're level 30s) and the next think i know, i hear that iconic "back-stabbing" sound, I stop what I'm doing and the very next thing i know I'm being back stabbed. It's like the guy teleported to me. I was far away from my party. He could have easily just killed the summoner, but he went for the two phantoms first. I'm so confused. He was invisible, I couldn't see him, and he was behind me with no tell-tale signs. What the hell? What sort of item makes you completely invisible? Isn't that cheap!? I feel horrid that my summonder died. I take pride in protecting my summonder. I know it was a bad idea to leave him, yes, that's my fault, I wont ever do it again, but come on. This assassin was so fast, so quick. It was only 3 seconds after i heard the first backstabbing that he got me. I'm wigged out, depressed, and sad. Has this happened to anyone else? Has anyone experienced a completely invisible invader???
