Here's how to use it: launch the scanner, then start a new game in Heroes. After 10-20 seconds, minimize Heroes (Alt+Tab). Then, select the desired hero from the list on the lower left. The large window on the right shows the skill tree. When you've selected a hero, click the plus signs next to them, and a window will appear showing what you receive at level 1. Click the plus sign next to the desired ability, and a window will appear showing what you receive at level 2 if you choose that ability.
