Skills for an Inferno hero.

I’m not arguing about fire resistance; it’s a useful skill against demons, and you’ve explained it well. What I mean is that while Hellfire is almost always taken, is the skill “Withering Flame” really that necessary? Spending 4 levels to enhance a skill that isn’t very strong right now seems wrong to me. Cutting back on Light and Hellfire will also affect Fireball of Pit Lords and the skill of the Fire Lord, and it will protect against dark magic if a demon happens to use it, so it seems very questionable to go with Chaos for a demon.
