Aberration Hunter

[Palanan]

What sorts of options does Pathfinder have for a dedicated aberration hunter? I’m aware of the slayer archetype, which looks interesting, but I’m wondering if there are other options available for druids or rangers.

I’m thinking of a druid who specializes in exterminating aberrations, and right now some combination of druid/slayer seems promising. Are there any options for the druid that would help with this? Or other, non-druid options that are too good to pass up?

While Pureblade is quite good, the combination of Ranger 1/Druid 5 with the Shapeshifting Hunter feat allow you to progress Fav.Enemy based on your combined Dru/Rgr levels. Add Fav. Enemy Spellcasting (Abberrations) and you're golden.

I should've mentioned, first-party Paizo only.

Any other suggestions from official Paizo material? I feel like there's got to be more aberration-hunting material out there.

The Green Scourge (https://www.d20pfsrd.com/classes/core-classes/druid/archetypes/paizo-druid-archetypes/green-scourge-druid-archetype/) druid fits the bill. Detect aberration (https://www.d20pfsrd.com/magic/all-spells/d/detect-aberration/) is also a druid spell. If you are specifically anti aboleth, you could go with gillman as a race. Gillmen also have a racial feat (https://www.d20pfsrd.com/feats/general-feats/aberration-bane-caster/) that helps cast against aberrations. Drow and gnomes have alternative racial traits specifically against aberrations.

Alchemists have a few things that fit, but mostly relating to oozes. The cavalier/samurai order of the green (http://www.d20pfsrd.com/classes/base-classes/cavalier/orders/paizo-cavalier-orders/order-of-the-green-cavalier-order-2/)gives bonuses against aberrations and undead.
