You got Repetate down.

Repetate: Cast it at a spot you were previously at, do what you were plannng to do, and if you mess up, you can transport back to where you were before you made that choice. and get another shot at it! Does not appear in multiplayer.

As for Retaliate, you're very close, but what activates it happens when you lose a lot of health........
