Invaded the world of some shitty guy in Lothric Castle who was wearing the Fallen Knight set in the Way of Blue covenant. After a few minutes of running around randomly, I figured out that he was still in the beginning of the area waiting for me to come to him. When I arrived, a Blade of Darkmoon had already been summoned to defend him from me. I was no match for both of them at the same time, so I backed up a little bit to get closer to some of the Lothric knight enemies. Naturally, the host wasted no time in using a Seed to make them attack me as well, because apparently having actual good players to come and help you whenever you get invaded just isn't defense enough. After a moment of being on the defensive as I was attacked by several enemies as well as the two players, I was able to find an opening to kill the Darkmoon blade, who had already been weakened by the knights. The host retreated back into the beginning of the area yet again, and I followed him, slowly managing to chip at his health with running attacks. After he stopped running, I was able to poise through one of his attacks, hitting him with a good combo just as yet another darkmoon blade was summoned. The host healed himself while his Blade attempted to kill me, but it went the same as last time. The host resorted to his final strategy of running in circles around the area while I hit him with running attacks, sometimes making an effort to hit me to mix things up a little bit. ANOTHER blade of darkmoon was summoned, but he returned home immediately for some reason. ANOTHER blade of darkmoon was summoned after that, this time standing right next to me, but by now the host had already run out of estus and I combo'd him to death in front of the Blade's very eyes. For some reason, he continued to try to attack me even after the host died, so I applauded to him.

How is it that whenever I invade people they get blue phantoms every 5 seconds but I still never get summoned as one?
