This function brings an Actor back to life. His stats and inventory will be reset, basically he "respawns". There is a bug when you use this function on the player – it will stop the PC (and all Actors) from casting magic. After saving and reloading this side effect goes away.
Note: The Puzzle Canal Script shows an alternative: it simply uses GetHealth <10 to determine when player is "nearly" dead and then "resurrects" him by giving him his health back – so the player actually never really dies.
Sample Script: some people are just tougher than others…
