Mind 3 can deck the opponent with a Psychic Blast, as in the feat of that name detailed in the Uncanny Influence section, p. 122. Life 3/ Mind 3 can turn that into a Psychic Shatter, as described in the same section. The Mind 2 variation is generally coincidental, but the brain-shredding “shatter” is distinctly not.

In this feat, the real damage comes from the psychic attack, not from the physical blow – see Violence as a Focus in Mage 20, Chapter Nine, p. 413. Story-wise, this could be the proverbial “heartbreak slap” that hurts more on the inside than on the outside.
