Launch the game, then the trainer (this is important). Turn on the functions you need and explore the world of the Witcher.

In terms of endless lives, it is better to use 1 function rather than 2, so as not to accidentally make enemies immortal (sometimes it happens). I set all the items to 99 mainly so as not to give Kalkstein the only stone for teleportation in the story. This way you can teleport to places of power whenever you want. If you enable the Enemies do not attack option, then Geralt will not be able to fight. But he can stand, think, and heal. As for the displacement along the coordinate axes, you need to press the buttons while the character is moving. But if as a friend Geralt moved to a place where there is some kind of obstacle (a fence, a barrel or someone’s house), then Geralt will stand near it and will not be able to move.

Save often!
