I was in Lower Undead Burg around level 30, so I decided to summon a phantom to help me with the Capra Demon.. I was at the beginning of the level, and summoned a Sunbro. I could tell he/she was a Japanese player because of their name. After a few seconds, he got summoned and we proceeded through the level. After clearing our all of the dogs and the bandits, we went to the gate. I realized the phantom was AFK because, well he wasn't moving. A few minutes later he sent me a message on PSN, saying: "Come follow see secret". I replied immediately with an "ok" because I was excited.. I followed him towards the wallside of the lower burg, and we came across a pathway that was blocked by wooden planks and stuff. The phantom stood there for a few minutes and replied to me "Look here secret". I replied with another quick "ok". Another minute or so passed by and the Japanese dude hit the wall with his claymore (Idk what stats it had maybe +5?). Surprisingly, the wall disappeared, and had the same animation most bosses do when they die, like the white stuff flying everywhere. There was a long road after the imaginary wall. It seemed to be bugged because it was a copy of a road after each 10 steps.. idk it looked really weird to me. At the end of the pathway was a chest. I was having a mini heart attack at this point. I opened the chest, picked up the item, and bam. Loading screen popped up and after that I'm back at the last bonfire I used.
WHAT THE F**K JUST HAPPENED?
