A mind drinker doppleganger can absorb the memories and skills of its victims, and you have inherited some of that power.
Prerequisites
Monstrous Bloodline (Doppleganger), Mind Reading, bloodline level 1st.
Benefit
As a standard action, you can make a melee touch attack to deal 1d2 points of Intelligence damage to a creature. A successful Will save (DC 10 +1/2 your Hit Dice + your bloodline level) negates the damage.
After damaging a creature with this feat, if the target has ranks in any Intelligence-based skills, you gain a number of temporary ranks in one of those skills equal to the amount of Intelligence damage you dealt, to a maximum amount equal to the number of ranks that the target possesses. These temporary ranks stack with any ranks you may possess in the chosen skill. You cannot exceed your maximum ranks in a skill, any temporary ranks beyond this limit are simply lost. These temporary ranks last for 1 hour.
You may possess a maximum number of temporary skill ranks equal to the number of Monstrous Blood feats you possess, including this one.
Special
If you have a natural weapon that uses your hands, such as a claw or unarmed strike, you can use a swift action to add the effect of this feat to an attack you make with that natural weapon. You must declare the use of this feat before making the attack.
