I see...what are these bastard mechanics possibly? Anyone wanna reference me some old ones? Im used to playing regular mafia
bastard can mean a mechanic that is not outdone by other mechanics
the most popular one is a jester role, a role that wins when lynched because it literally throws back town, even when towns strongest weapon is the lynch, taking away this weapon is considered bastard for example
as celestia mentioned town bus drivers can often be considered bad for town and thus such roles can be considered bastard
also alot of RNG mechanics or other host influence for the balance are considered bastard
also for the setup: it is clear we play the SS (Soul Society) arc, So Ichigo and team are mafia, Aizen and Rukia thirds.
So 10v1v1v13 is something I can imagine.
