Lucas' first use of this ability will be to increase his own physical strength without having any effect on his visible musculature. He will soon learn to use the ability on others too, increasing and decreasing their physical strength. He will be able to choose whether or not doing this will affect their musculature. With a greater effort, he will also be able to affect other strengths, such as the strengths of abilities or mental strengths. He will be able to effectively augment and negate abilities, though he will never choose to augment his own and will only rarely augment others. He will be able to increase a person's mental strength to help him or her resist the effects of abilities like telepathy and persuasion.
