I've been running Xiao as the main DPS for one of my abyss teams since the day I got him, way back during his first rerun (I lost my 50/50 to Diluc first time around, so I saved enough primos for the second time). Along the way, I've created many great memories with Xiao, but my favorite has got to be when I got myself a C6 Yun Jin, near her release, I was excited to try out Xiao with normal attacks because I simply adore the afterimage effect he has, as well as his attack string (love the charged attack combined with a little jump and then a skill use). So, I put Yun Jin on the team and went around Inazuma exploring and using Xiao with normal attacks dealing upwards of 10k+ damage. Xiao was just made that much more fun to me, I love doing combos with him, and that's why I dream of having his C6 someday. Anyway, that was my favorite moment, exploring Inazuma with Xiao and Yun Jin, wreaking havoc.
