Intuitive Aptitude (D20 Modern Feat)
From D&D Wiki
Intuitive Aptitude [Power]
The character also gains a “hunger” for other powers, and when within 100 ft. of another evolved being or when the character has knowledge of the existence of another evolved being he must make a Will save DC 10 + ½ character level + ½ the other evolved beings character level or attempt to take their power, using whatever means necessary. If you pass the save you are immune to this effect against that specific individual, unless something traumatic happens that would force you to make a new save DM decision. This effect is always active.
The character also learns to gain the powers of others faster but at the cost of the person the power belongs to. The character may study the brain of an evolved being for a number of rounds, up to a maximum rounds equal to the number of ranks in the power skill that the character has, to obtain that number of ranks in the skill when gained through empathy.Example: If Teresa, an empath, uses this feat to study the brain while using the Power (empathy) skill on John, a space/time manipulator with 10 ranks in space/time control, for 5 rounds, Teresa would obtain 5 ranks in space/time control. If she was to study for 10 rounds she would gain 10 ranks in the skill.
