Hero skill tree.

Maybe I'm wrong, but it seems like such a program is called "Heroes Scanner" (or something similar). When you launch the game with this program, it displays the hero's skill tree, which shows exactly which skills that hero will have in the game – quite a marvel! I downloaded this scanner from some professional review, but I only used it in single-player. However, the reviewer claimed that this program was almost a cheat and advocated for its removal.
