Feral Scavenger (Natural Explorer Archetype)

Some explorers are merely survivors who have learned the right lessons quickly enough to thrive. Alone, under-equipped, and desperately clinging to survival, the feral scavenger has learned the first explorer rule: adapt or die.

Weapon and Armor Proficiencies
The feral scavenger gains proficiency with simple weapons only. He is not proficient with any armor or with shields. This modifies weapon and armor proficiencies.

AC Bonus (Ex)
When unarmored and unencumbered, the feral scavenger adds his Wisdom bonus (if any) to his AC and his CMD, and he gains a +1 bonus to AC and CMD for every four class levels he possesses. These bonuses to AC apply even against touch attacks or when the feral scavenger is flat-footed. He loses these bonuses when he is immobilized or helpless, when he wears any armor, when he carries a shield, or when he carries a medium or heavy load.

Tooth and Nail (Ex)
The feral scavenger is used to fighting with simple weapons, and with his bare hands. At 1st level, he gains the unchained monk’s unarmed strike class feature, dealing damage as an unchained monk of his feral scavenger level.

This replaces explorative hunter.

Use of Weapons (Ex)
The feral scavenger is has learned to use whatever is at hand to defend himself. He gains the feats Catch Off-Guard and Nature’s Weapons as bonus feats, even if he does not qualify for them. The feral scavenger may do damage with improvised weapons equal to his unarmed damage. Whenever the feral scavenger gains a combat feat that requires that he choose a specific weapon or weapon group, he may choose all simple and improved weapons and unarmed as a single entity. At 1st level, he gains the Weapon Focus feat for all simple and improved weapons and unarmed strikes as a bonus feat.

Bone Blades (Su)
The feral scavenger can cause hardened blades of bone to extends from his hands, forearms, and possibly his feet as well. His unarmed attacks threatens a critical hit on a roll of 19 or 20 (this may be modified by effects such as the Improved Critical feat), and he may do bludgeoning, slashing and piercing damage with them.

Feral Strike (Su, 4th level)
As a swift action, the feral scavenger can imbue his weapons (natural, improvised, or otherwise) and his unarmed attacks with a fraction of his feral power. For 1 minute, his weapons have a +1 enhancement bonus to attack and damage rolls. For every five class levels he possesses, this bonus increases by +1, to a maximum of +5 at 20th level.
