Unusual AnatomyFocus 5
Source Pathfinder Player Core 2
Cast

Duration 1 minute
You transform your flesh and organs into a bizarre amalgam of glistening skin, rough scales, tufts of hair, and tumorous protuberances. This has three effects:
- You gain resistance 10 to precision damage and resistance 10 to extra damage from critical hits. If the resistance is greater than the extra damage, it reduces the extra damage to 0 but doesn't reduce the attack's normal damage.
- You gain darkvision.
- Acid oozes from your skin. Any creature that hits you with an unarmed attack or with a non-reach melee weapon takes 2d6 acid damage.
Heightened (+2) The resistances increase by 5, and the acid damage increases by 1d6.
Spell Effect: Unusual Anatomy
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
FocusFocus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
ManipulateYou must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
PolymorphThese effects completely transform the target into a new form. A target can't be under the effect of more than one polymorph at a time. If it comes under the effect of another, the second effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items. You lose your Speeds and gain those of the battle form. If a polymorph effect causes you to increase in size, you must have space to expand into or the effect is disrupted.
SorcererThis indicates abilities from the sorcerer class.
