how can i teleport a player when hit by an enemy

Well, it actually won't because as soon as the if statement passes (first time at 75 health), return is called which makes it not loop anymore.

I suggest not running this loop until you spawn the monster, for the sake of performance. Then I'd also change the timer countdown to 0.1 seconds to actually make sure the player is teleported instantly and not after one second.
