Beastshifter, a Pathfinder RPG Base Class in 2 paragraphs + 1 sentence.
Beastshifter: The beastshifter is a base class that grants a warrior-type character access to animalistic shapechanging powers. Use hit dice, proficiencies, class skills, skill points per level, base attack, base saves, starting wealth, and starting age as a barbarian.
Gain the animal focus class feature as a hunter of your class level, but you can use it for 1 hour per class level. This duration need not be consecutive, but it must be used in 10 minute increments. (If you somehow gain an animal companion, your animal focus ability does not apply to it). While using animal focus you gain +10 foot move, and may either gain a bite (1d6 primary attack if Medium) or two claws (1d4 secondary attacks if Medium), as decided by you when you use the ability. Beginning at 4th level you may use two animal focuses at once, or instead use wild shape as a druid of your class level (which counts against your animal focus duration). You cannot become an elemental or plant. At second level, and every two levels thereafter, you gain a rage power as a barbarian of your class level. You can only use rage powers while in animal focus or wild shape. Rage powers useable once per rage can be used only once per hour, and you cannot gain (or improve) the true rage class feature of a barbarian.
You gain no other class features. #QuickBaseClass
