Hello, guys! Can anyone tell me, for example, i made a set and i want to try it with other forces/relaxes? how can i switch em?

You go into your own custom folder and edit item.dat. Use this list of colors http://toribash.com/colors.txt and either work things out on yourself (it's easy) or use some tutorial like here: http://forum.toribash.com/showthread.php?t=195093
