No real need for a trainer just learn how to use a memory editor(Artmoney). I've been using these types of editors for several years now.
The skill points are located in the "Integer 2" value and easy to find since you start with 9 skill points. So if you give yourself 50 skill points you can easily get 10k hp/mana at the start of the game.
-Look for a value you want to change for instance your skill points which is nine at the start of the game.
-Then alt+tab to Artmoney and click the down arrow to the right of the box next to where it says: Select Process. And select your game process.
-Then click on Search and a box will appear.
-Make sure you search on exact value and then click on the button with "..." in it since it will bring up a custom search box.
-Now you will see selection boxes where you can decide what values to search for. In this case I know that the skill points are located in the integer 2 value so make sure that is selected and then press ok to leave that box.
-Now in the value field of the previous box you input the value to search for, which is 9 and then you press OK.
-Now the program will search the memory for all values of 9.
-Once the search is done go back into the game a spend some of you points so this value changes. And then alb+tab back into Artmoney and click on FILTER.
-This time input your new value and it will filter through your previous search to match the new value.
-And repeat this process by going back into the game and change the value then back out to Artmoney and do FILTER until you only have 1-3 matches left.
-Then you press the green arrow button to move all the matches to the right and once there you just edit to what value you want and then when you get back into the game again you will have the new value you decided on.
-Skill points are on Integer 2 and Resources are on Integer 4. But if you don't know on what value something is you have to search on them all or take a chance on a value you think it might be.
Maybe it seems complicated but it's really simple when you have done it a few times.
It's not a lot of work. It will only take about 40 seconds if you know what value to search on. And once you change values for gold & skill points you will have it forever once you save the game so not like you have to do it again.
It can be much work if you want to resource cheat since you have to search on every new map.
