So basically... The second DL ability is to skip up to 10 seconds forward in time. To everyone else in the world he follows his fated actions and then suddenly warps back to his original position and velocity, but to him the world jumps forward instead of him. If he is hit during this time, then he heals, but if he ends up inside an object, then if it's moving he will be "hit" by it, but if it's not then to DL he just snaps out of the box. This prevents him from just skipping time to evade a big boulder from crashing down on him or something like that.
Actions speak louder than words PLZ GIVE FEEDBACK IN COMMENTS Took me roughly 1h 30min with a slightly annoying kid by my side...
