Skills for an Inferno hero.

Since summoning gates is a very powerful ability, various skills are needed, so in my opinion, it should be:
1) Luck up to wide gates (if you're lucky).
2) Diplomacy up to the gate guardian.
3) Logistics up to fast gates and surprise attack.
4) Chaos up to fiery wrath.
5) Or attack or ballista, depending on the hero.
