In my game, I want my players to travel throughout maps in my game with the same tools. I'm looking for a way that the players can have the same tools without having to find them again in the other maps.
Are the "maps" different places within the same game universe? If so, use data stores to store the player's data on the tools they own.

If you're talking about "maps" that are in the same game and place, but just in different locations, you might be killing the player for them to teleport, causing them to lose their tools. What you can do instead is teleport the player's character by changing the character's HumanoidRootPart CFrame to the desired location.
