From my side it was when we entered a town of friendly ghosts and the bard suddenly started to flirt with a store owner (also a ghost). That person still gets to hear "well at least I don't try to get it on with a ghost" as a joke XD
@BrokenBonessa Let's see, I literally am a bard and bards are my favourite class, so I got about a million stories. How about the time my 20th level bard single-handedly diffused the first encounter of the game, then true polymorphed a wagon into a silver dragon she befriended to add to her menagerie. Which already included a sabre toothed tiger and a hawk. 20th certainly is something else.
@artisticfennec sounds amazingly fun😆​ I haven't played for so long so I don't know what level 20 brings. I hope I someday find out.
@BrokenBonessa My DM decided to run a Level 20 campaign. I felt his soul leave his body when I did all of that.
