Notes:

The Arseplomancer is my favourite custom class because of just how f------ dumb it it is.

Basically, it boils down to an athletic skill called Persuasive Performance, which is supposed to be used by a Diplomancer in order to sway their opponents to their way of thinking.

The Persuasive Performance allows the arseplomancer to also make this escape artist check act as a diplomacy check for improving attitudes as long as the onlookers are within 30 ft. A sufficiently high diplomacy check is able to turn onlookers into fanatics (the difficulty varies depending on the starting attitude), thus turning ordinary people into (sadly temporary) devoted disciples of this mighty super-man who can leap into assholes.

They then use a Growth ability to cause the victim to explode.

The footage I used to make this comes from here:
