Tieflings are iconic with their tails though, but I don't see why it couldn't have been cut off during their time before an adventure either in a fight, accident, etc. Or just a genetic flaw or whatever backstory fits 😋
I like my Tiefling better with no (mandatory) tail. More specifically, I like my Tieflings as having,
usually,
some visible modification/mutation/variation. It might be a tail, some horns (big like in BG3 or more discreet), a different skin colour, weird eyes, a different eye colour, a different (un-dyed) hair colour, 6-fingered hands ... or a mix of several or all of those. Something different, unnatural/unusual, something that sets them apart as being Tiefling/other. But nothing set in stone, like the standard full Devilish look.
Perhaps obviously, I prefer my Tieflings to be generally anyone plane-touched or magic-touched, rather than only Devil-kin.
since we do have a "hornless" option
Has the hornless option improved ? Or does it still look very visibly like horns that were cut ? Because no-horns and cut-horns are definitely not the same.
