Create a new character.
Create a witch.
Select a hex that targets an enemy.
Attempt to take Ability Focus for hexes.
Ability Focus allows you to use any spell-like or supernatural ability as a prerequisite.
I believe it affects all hexes, as the hexes are all under a single ability, and they would be affected by anything that changed that base ability. Do you still need the list? If so, I'll provide it. Just want to make sure it's done right.
I'm a little leery of granting a DC boost to all hexes, in all other cases, it's a single ability, not a group. Can we find a rule or FAQ that answers this question so I know the official stance.
I can't find anything official; most people say that it only affects one simply on the basis that it's "too good" (despite other options being just as strong)... so how do we call it?
I'll implement Witch Hex for now, I sent a note to the Publisher Liaison to clarify the rules.
If there are other "Class Features" missing, please open a new Data Request Tracker.
