I know this isn't anything to good players. But I completed a solo run on my own just now. I needed to do a quest for Ironeye, kill the invader. I figured I could just do it on day 1 and then die and complete the step. I rushed him at level 3 with no special bow and got my ass kicked. Left my runes and completed day 1. I was surprised that I was able to finish day 1 honestly. My boss was the lil yoda flea dude and the big one. Got to level 8 and went back to do my quest. Didn't have all that much but decided screw it, might as well at least TRY to finish. I missed out on one flask and was just using the ONLY bow I found the entire run. Upgraded it to purple and beat night 2 boss, the three horsemen. Got to level 12 and went to fight the boss. I specifically picked the dog boss because at the time I didn't think I'd ever get to the final boss so I didn't care. I am really bad at souls game but this one is really addicting.
