Ok so some people think Blackmailing is too weak (I don't agree) but it made me think of a role that if implemented, might make the Blackmailing buff worthwhile.
Bastion is a town protective that is a martyr. He's like Beguiler but in reverse. Whatever was supposed to happen to the target instead happens to the Bastion.
He could pull blackmails off people, sacrifice himself for a more important role, cover a Sheriff that is getting RBed by a Consort, you name it.
Whatever Bastion wants to do, he will take the fall for you.
