Certain characters and creatures are able to automatically dodge an attack without using up a melee attack/action. It is purely a defensive move in which the dodger bobs, weaves, bends or twists their body out of harm's way.
Roll the Dodge as normal (the Automatic Dodge is an automatic dodge attempt, not an automatic sucess).
An Automatic Dodge works just like an (automatic) Parry in that the act of dodging does not use up any attacks to perform. Bonuses to Automatic Dodge come from the character's P.P. attribute and any special bonus specifically for it (the bonus skill or enhancement will say 'Automatic Dodge'). Unless it specifically says a character has Automatic Dodge, they do not.
