Effect The familiar steps haunt is triggered when a spellcaster with a familiar enters its area. The spellcaster’s familiar wanders into the most crowded area nearby (no save), prompting its master to follow (DC 20 Will negates). Each turn spent in a square occupied by a creature of Small-size or larger prompts a Reflex save from minuscule and infinitesimal creatures (DC 25) or they are unknowingly trampled by the regular folk (1d4+3 bludgeoning damage, Fort DC 20 or knocked prone). Prone creature take triple damage from the familiar steps haunt. After being trampled by due to the familiar steps haunt, a creature must make a DC 20 Will save or be compelled to travel in a random direction (roll 1d8).
Destruction The remains of the familiar once belonging to Vagraxxa the Vivid (another mage that attempted to teleport into Mohkba against the will of the Sanctioned Arcane Practitioners) must be exhumed from the foundations of a building nearby, ground into dust, and used as a spell component in order to permanently destroy the familiar steps haunt.
