Subtype Specialization: A Pokémaster can choose a subtype which is her specialty. A Pokémaster gains a +1 bonus on all Bluff, Handle Animal, Knowledge, Listen, Sense Motive, Spot, and Survival, checks when using these skills on or about such creatures for every 3 caster levels she has. A Pokémaster can choose a second Subtype to be equally proficient with at 12th level, and a third at 18th. A Pokémaster can Control one extra Pokémon which must be of a subtype that she specializes in. Subtypes include: Air, Aquatic, Chaotic, Cold, Earth, Electricity, Evil, Fire, Good, Lawful, Reptilian, and Water.
Increased Awareness: At 4th level and above, a Pokémaster's Pokémon become more intelligent and aware. After the Pokémaster has owned her Pokémon for at least 1 week, its intelligence changes to the Pokémasters ranks in Handle Animal if that is more than its normal intelligence.
In addition, a Pokémaster can make her Pokémon gradually see things her way - a Pokémon's alignment shifts one degree towards the Pokémaster's each week if she can succeed in a Handle Animal check at a DC of (10 + the Pokémon's CR). The DM decides whether it moves Law/Chaos or Good/Evil first depending upon circumstances. So if a Lawful Good Pokémaster captured an Imp (lawful evil Pokémon), the Imp could become Lawful Neutral after one week, and could be Lawful Good after 2 weeks. Pokémon subtypes are unaffected - so a Evil Pokémon such as an Efreet would stay subtype Evil even if it subsequently became of Good alignment.
