The RaW for the White-Haired Witch archetype definitely raise more questions than they answer:
--Does the hair attack receive the Intelligence bonus to hit as well as damage? This only seems to make sense. Also, the wording "plus the witch’s Intelligence modifier" seems rather open-ended...is this in addition to a Strength modifier to damage? If so, since it is the only primary natural attack, would that be 1 1/2 times Str mod to damage (or for that matter, 1 1/2 times the Int mod)?
--Since it is a Free action to grapple an opponent on a hit with the hair, can the Witch then use a Full Attack action to attack the grappled opponent with a weapon in that same (first) round? (Obviously she could not do so in subsequent rounds, because at that point maintaining the grapple would require a Standard action.) If she can do this, is the weapon considered a secondary attack?
--Since the Witch is not considered to have the grappled condition when grappling a foe with her hair, if her hair had reach, would she still receive attacks of opportunity with her hair against other foes provoking with movement? If so, could she grab/grapple them as well? Or is the hair considered to be completely occupied when grappling one foe?
--If the Witch hair-grapples a foe at reach (10', 15' or further away), does the foe remain in the square they were grappled at that distance, or are they automatically pulled to a square adjacent to the Witch, as per usual grapple rules? (Since the RaW explicitly state the Witch is NOT considered grappled, and since there is a special "Pull" hair attack available at 6th level WHW, it seemed to me that said grappled victim would simply be stuck in the square in which he was grappled...unless perhaps he won a grapple check and used the option to "move yourself and your target up to half speed", thus allowing him to move closer).
--What kind of damage does hair do: B, P, S, or some combination?
