"Your blood, your marrow, your spirit—all are mine."
—Mayvar, minion of Geth

10/1/2009: The amount of life you gain is equal to the number chosen for X, not the amount of damage Consume Spirit deals (in case some of it is prevented).
10/1/2009: If the targeted creature or player is an illegal target by the time Consume Spirit would resolve, the entire spell is countered. You won't gain any life.
