Antares has the following traits from studying the dragon school:
Claws (Su): Starting at 2nd rank of the dragon school, you can grow claws as a free action. These claws are treated as natural weapons, allowing you to make two claw attacks as a full attack action using your level as your attack bonus. Each of these attacks deals 1d4 points of damage plus your Strength modifier (1d3 if you are Small). At 5th level, these claws are considered magic weapons. At 7th level, the damage increases by one step to 1d6 points of damage (1d4 if you are Small). At 11th level, these claws deal an additional 1d6 points of damage of your energy type on a successful hit. You can use your claws for a number of rounds per day equal to 3 + your Intelligence modifier. These rounds do not need to be consecutive.
Dragon Resistances (Ex): At 3rd level, you gain resist 5 against your energy type and a +1 natural armor bonus. At 9th level, your energy resistance increases to 10 and natural armor bonus increases to +2. At 15th level, your natural armor bonus increases to +4.
