Lycanthrope is an inherited or acquired template that can be added to any humanoid, monstrous humanoid, or giant (hereafter referred to as the base creature). The lycanthrope takes on some of the characteristics and features of a creature of the animal type (hereafter referred to as the base animal). The base animal can be any carnivore or omnivore within one size category of the base creature.
Size and Type: The lycanthrope's type does not change, but it gains the shapechanger subtype. It's size depends on its form. In either humanoid or hybrid form, it's size is that of the base creature. In animal form, it is the size of the base animal.
Hit Dice and Hit Points: While in animal form, the lycanthrope gains bonus hit dice equal to that of the base animal's hit dice total (minimum 1). These grant commensurate temporary hit points (applying the lycanthrope's constitution modifier, if any, to those hit dice). The lycanthrope also gains a competence bonus on attack rolls equal to the base attack bonus of the base animal as well as competence bonuses to each saving throw equal to the respective base save bonuses of the base animal. A lycanthrope's normal hit point total is determined by using its constitution score while in animal form.
Speed: In humanoid or hybrid form, the lycanthrope possesses the movement modes and speeds of the base creature, while in animal form, it has the movement modes and speeds of the base animal.
Armor Class: In humanoid form, the lycanthrope gains a natural armor bonus of +2, unless it already has a higher bonus. In hybrid or animal form, the lycanthrope has a natural armor bonus equal to that if the base animal (if any) +2.
Attacks: The lycanthrope retains any attacks of the base creature while in humanoid form. In either hybrid or animal form, it gains the natural attacks of the base animal. A hybrid lycanthrope may also use weapons.
Damage: Same as either the base creature or base animal depending on form. If the lycanthrope's hybrid form is a different size from its animal form, it's natural weapons are either increased or decreased by a die step if larger or smaller, respectively.
Special Attacks: A lycanthrope possesses either the special attacks of the base creature, if in humanoid or hybrid form, or the special attacks of the base animal I'd in hybrid form. A lycanthrope in animal form cannot cast spells. While in hybrid form, the lycanthrope can cast spells but cannot perform any somatic components. In any form, a lycanthrope can manifest powers.
Curse of Lycanthropy (Su): Any humanoid, monstrous humanoid, or giant hit with one of the lycanthrope's natural weapons while in either hybrid or animal form must make a Fortitude save or contract lycanthropy. The save DC is 10 + 1/2 HD and includes the bonus hit dice from the lycanthrope's animal form. The target cannot contract lycanthropy if it is not within one size category of the lycanthrope's animal form.
Special Qualities: The lycanthrope retains all special qualities of the base creature in all forms. In hybrid and animal form, it gains the special qualities of the base animal. A lycanthrope who embraces the curse gains all of the base animal's special senses while in humanoid form. These include (if applicable) scent, low-light vision, darkvision, tremorsense, blindsense, blindsight, and any racial bonuses to spot and/or listen checks.
Alternate Form (Su): A Lycanthrope can assume the form of a specific animal. It does not gain the physical ability scores of the base animal but, instead, applies the animals ability score modifiers to its own. The lycanthrope may also adopt a bipedal hybrid form with animalistic features. In this form, the lycanthrope also gains the ability score modifiers of the base animal.
Changing between forms is a standard action.
A slain lycanthrope returns to its humanoid form, but any separated body parts retain their transformed appearance.
A lycanthrope who has embraced the curse can change between any of the three forms at will. However, those who are either ignorant of the curse or reject it cannot freely transform. Every night, there is a chance that the lycanthrope may adopt its animal form. This chance is dependant upon the fullness of the moon. A new moon has a 0% chance. A crescent moon carries a 25% chance. A quarter moon comes with a 50% chance. A gibbous moon possesses a 75% chance. Finally, on nights of a full moon, there is a 100% chance of transformation.
When a lycanthrope unwillingly transforms, it loses all control of itself and becomes naught but a wild animal until dawn when it returns to its humanoid form. A lycanthrope who is aware of the curse can attempt to resist these transformations with the control shape skill.
Damage Reduction (Ex): A Lycanthrope in hybrid form has damage reduction of 5/silver. This increases to 10/silver while in animal form.
Lycanthropic Empathy (Ex): In any form, lycanthropes can communicate and empathize with normal or dire animals of their animal form. This gives them a +4 racial bonus on checks when influencing the animal’s attitude and allows the communication of simple concepts and (if the animal is friendly) commands, such as “friend,” “foe,” “flee,” and “attack.” A lycanthrope in humanoid form can only use this ability if it has embraced the curse.
Beastial Pride (Ex): A lycanthrope who has embraced the curse gains a +2 bonus on Will saves in all forms.
Abilities: When in hybrid or animal form, a lycanthrope’s physical ability scores improve according to its kind. These adjustments are equal to the animal’s normal ability scores -10 (if even) or -11 (if odd).
Skills: A lycanthrope who is aware of the curse gains control shape as a class skill for all classes. A lycanthrope who has embraced the curse gains all skills listed in the base animal's description as class skills for all classes. If the base animal has any racial modifiers to skills, the lycanthrope gains these while in hybrid or animal form.
Alignment: A lycanthrope's alignment is that of the base creature. If the lycanthrope embraces the curse, its alignment shifts to chaotic as it unburdens itself from civilization and gives in to primal instinct.
Level Adjustment: +0 (If unaware of or rejecting the curse), +1 (If the base animal has 5 or less HD), +2 (If the base animal has between 6 and 15 HD), or +3 (If the base animal has 16 or more HD)
