I Reincarnated in Lorien Legacies(I am number four.)

Freya or Number one

1) Earthquake generation

2) Light Spectrum perception

3) Paralysis Inducement

Maggie or Number two

1) Technopath

2) Phasing

3)She has the power to emit powerful concussive sonic blasts.

Number three or Humma

1)Electric touch, he can send an electrical current across his or her skin, allowing him or her to administer mild jolts to deadly shocks to anything he touches.

2) He possesses greatly enhanced physical senses to track people for miles.

Now give me some ideas for any new abilities for them. Even though I missed an important point which is generally the most powerful Legacy is usually developed last, known as the "Master Legacy" and is combat-focused.

So which legacy to give these three?
