It's a weird type of quest you, as the playerbase, try to roll to make the QM salty or tear up a bit inside. That is if I remember it correctly. And the player rolls a DX roll where the X is the number of characters that can cause mayhem and a D100 to see how successful they are at doing it. The options are unlimited. All for salt.
.....And our good QM here rolled 90 in order to get a Sith Lord reference Servant in FGO into the list of 'mayhem inducing characters'.
