My friend and I thought that it wuld be pretty cool if when a pentakill champ ults a tune starts to play. They play the tune with their instruments and if by some divine spirit all pentakill champs are in one game and ult at the same time they start to play a song. just an idea we had after he played Pentakill 
and I played Pentakill 
Acerola2 votesCan't imagine it happening, but I'd absolutely love if it did. Any in game music-related stuff with the Pentakill skins in any way shape or form would be great. I'd especially love for Sona's ult to get some nice Pentakill music, since the current sounds don't fit well.
YDrahgonz132 votesYeah, especially for sona. Her current sounds don't match the theme

YDrahgonz132 voteslol, that would be pretty sweet
