Skills for an Inferno hero.

No, you can't rely on a demon's empathy. With only 2% Education and 2% Leadership... and since that's the case, it's also not worth investing in Counterspell. In my opinion, you need to plan your skill progression with those skills that have a decent chance of appearing. I've never understood, for example, those who say they level up summoning magic for a Light Elf, etc.
