Player: Mini
Character: Alexander Varista
Reason for Echo: (1) Meeting the Sage and (2) bat-trap.
What is returned:
(1) An additional 25% of his regenerative ability.
(2) Hypnotism. From his app:

He is able to put a person or an animal in a trance. While in the trance, he can make simple demands, like retrieving the newspaper from outside. He cannot make complicated demands, like filling out the crossword section. Depending on the person, some actions may or may not constitute as complicated. For example, someone who is comfortable with driving will drive under his order, but someone who is still learning will not because there’s more thought that goes into the action for them.

He must make eye contact to hypnotize someone/something.
