well.. it'S a tool with which you can search for gamevalues.
first start HG:L, then start artmoney and choose in the prozess line your HG:L prozess.
Now it depends what you want to do. If you want to modify your experience (and therefor your level as well your avaibly skillpoints) you change go into the game (game have to run all the time) and look for your current value. Now you swith with alt/tab another time to desktop, choose search and search for the value (options that worked for me are 'exact value' and 'all - standard'). Now artmoney gives you many adresses with these values. To shorten the list you have to play a short time to change the current value, skip to desktop use the option 'filter' (don't know if it's the rigtht naming for the english version, but it's the one right from search ). Here you use the same options as before. If you have just one adress left doubleklick on it so that it come to the right window where you can change the value and freeze it (for xp you will have to get experience one more time to get your levels).
Maybe you have to do several trys for one attribute because you maybe won't have any adress left in some trys, but in the end it worked fine for me for money, xp/lvl, free skillpoints as well as free attribute points
