You are specially trained in combating the world’s vermin and have little to fear from the swarms of creatures that are a lethal threat to less capable warriors.
Prerequisites: Favored Enemy (vermin)
Benefit: You do not suffer automatic damage from being in a swarm’s space, nor are you sickened by sharing space with a swarm.
Scientific Fighter (Combat)
You fight in a meticulously planned style that maximizes your effectiveness and emphasizes precision and speed over brute strength.
Benefit: With a light weapon, rapier, whip or spiked chain made for a creature your size, you may use your INT modifier instead of your STR modifier on attack rolls. If you carry a shield, its armor check penalty applies to your attack rolls.
Special: Natural weapons are considered light weapons.
You know how to trick your dimwitted opponents into leaving themselves open for a devastating wound.
Prerequisites: Scientific Fighter, Combat Expertise
Benefit: When facing any creature who suffers an INT penalty with any weapon for which your Scientific Fighter feat applies, you may add that creature’s INT penalty as a bonus on weapon damage rolls.
Tough Familiar (General)
Your familiar has little to fear amid even the worst fray, and leaps to defend you in battle.
Prerequisite: Familiar class ability
Benefit: Your familiar immediately gains an additional amount of Hit Points equal to your character level when you select this feat, and one HP per level thereafter. Your familiar’s natural weapons are treated as magic for the purpose of overcoming damage reduction.
Ferocious Familiar (General)
Your familiar is a dangerous and tenacious combatant whose threat is far out of proportion to its size.
Prerequisite: Tough Familiar
Benefit: When within 30 ft of you, your familiar receives a +1 morale bonus to attack and damage rolls with its natural weapons. This bonus increases by +1 for every five character levels you possess, to a maximum of +5 at 20th level.
