We can make a free Touch Attack on the same turn we cast a Touch Spell.
If we hold a charge, a Touch Spell can also be delivered via Unarmed Strike/Natural Attack.
Is there anything that states the free Touch Attack must be done by hand? Can we, for example, use WHW's hair to deliver it via a Touch Attack (not a Natural Attack, e.g. no damage)?
If yes: would this count as the hair landing an attack and allow WHW to get her free grapple attempt?
I stumbled upon this Archetype that looks terrible on paper but I'd love to theorycraft something workable; without her hexes, WHW still can play a wizard-like role, and if WHW can land an attack with her hair against Touch AC (since she'd have terrible BAB and STR, maybe workable dex+finesse), she can make a grapple attempt from up to 30 feet away, and since she gets Rogue talents at lv. 10 and above, she could get Maneuver Mastery, which would let her apply her Witch level instead of her BAB to her grapple checks. Her archetype also already allows her to use INT instead of STR for grapple checks with her hair. A Crab familiar could also give her another +2.
With more feats from Combat Tricks, she'd definitely be able to get Improved Unarmed Strike=>Improved Grapple=>Greater Grapple for another +2 and the ability to make the check as a Move Action.
With Throat Slicer, she'd be able to deliver a coup de grace as a Standard Action to pinned enemies.
So as a purely theoretical rundown possibility?
Turn 1:
> Standard action-Cast Touch of Fatigue (-2 to enemy STR), deliver with hair up to 30ft away, grapple as a free action.
> Move action-grapple check, if successful, inflict pinned condition.
Turn 2:
> Standard action-Coup de grace with a Warhammer(1d8/x3), ignores -4 from no proficiency since it auto-hits.
> Move action-Profit??
So now we have a caster that still has options like Black Tentacles, Glitterdust, Mage Armor, possibly Haste, etc., but without using up a spell, can set up a grapple from a range and has the feats to back it up while still maintaining full spell progression.
This is purely theoretical, and probably much worse than a normal Witch or Wizard, but seems like it could be a lot of fun if it works.
