What is the hook for map change.

What is the hook for a map change? I am making a XP System and i need it to save when the map changes and when they disconnect i figured out the disconnect but i could not find the map change hook on the wiki.

Thank you, one more question how do i add multiple hooks to Initialize a function

You should always add hooks through

hook.Add unless you’re making a gamemode.
