So, I've been sitting around, and eventually I came to think of converting the concept of the dark spuls 2 hexer to PF.
Hexers are exiled for thier art, for they commune with the darkest forces present in every human soul.
Hexers would always use the lowest of either int and wis or int and cha as their casting stat.
They make very good blasters.
Thier attack spells are more powerful then normal, at a few costs-
The split stat requirement mentioned above.
They cannot choose to fight defensively when casting a "staff" hex (most hexes used in normal play fall under this)
Devine foucs hexes can be cast defensively, and are even more powerful, but almost always have some sort of cost to the caster... And it's rarely as simple.... Or cheap... As gold.
Both always require a costly non-magical staff or holy symbol as a focus, the cost this focus needs to be raising as your level does. This focus qualifies as all cheaper focus components of the same type, however.
Thier most powerful spells can sweep most battlefields, but have a casting time of several rounds, during which point they can take a hit.
It's clear to most humans, even those without knowladge (arcana), when they cast, due to a distinctive hum right before the spell goes off that nearly everyone has learned to fear.
Thier spells would deal mostly untyped or bludgeoning damage.
There are very few spells they have that don't relate to directly dealing damage, but they can also prepare a small number of lower-level spells from the wizard or cleric spell lists (chosen at charecter creation)
Hexers have extraordinarily low hp, due to the rigors of their work, and only have d4 HD.
