Play as Inferno.

Does anyone have detailed information about the factions and creatures, and most importantly, about the heroes and the skills they can learn, and which ones are worth taking? =)

p.s. I've already read the one in the important topics.

p.s.s. I found one for Necromancers: http://heroes.ag.ru/heroes5/advices/11/
but I can't find one for Demons...
