The world really has to function as a game for his skill to function at all; it basically reduces variables to zero, with the first skill setting the respawn timer to zero, and second setting attack (possibly multiplier) to zero.
We'll know next chapter whether its attack power or multiplier which is zero (some stories have guns weak since they don't get stat multipliers applied, that its always a 0 attack gunshot), so does he still have to deal with this few hundred pound arm slamming him down, or less than a breeze.
