Ritual of the Dark Infiltrator (Su): By undertaking a daylong ritual known only to the anarchomancers of the Revolutionary League, the anarchomancer can transform herself into a completely different character-one with a different race, class, and even abilities the anarchomancer does not possess herself. Using the Ritual of the Dark Infiltrator costs 1,000 gp and drains the anarchomancer of 1,000 XP. The ritual takes 24 hours, during which time the anarchomancer must be undisturbed.
When the ritual is finished, the anarchomancer chooses a new form, essentially creating a second character that she'll play instead of the anarchomancer. Calculate the anarchomancer's base Leadership score according to the rules for the Leadership feat in Chapter 4 of the DUNGEON MASTER'S Guide, the second character is constructed as if it were a cohort appropriate for a character with that Leadership score. Don't apply any reputation or leadership modifiers (great renown, has a familiar, and so on). The second character retains the memories, motivations, and goals of the anarchomancer's previous life, but she can't cast spells or use racial abilities that she does not possess anymore. Nothing short of a wish or miracle reveals the new character's former life as an anarchomancer. The anarchomancer gains new levels according to its character level as an anarchomancer, even if the second character is lower level.
As a full-round action, the anarchomancer can return to her original character, shedding the original body in a burst of eldritch power.
