Skills for an Inferno hero.

I wouldn't say so... the durability of stone isn't that great without light... even with +9 to defense... and you can learn it in Light, although it drops at level 15+. Besides, creating a stone golem will cost you 12 mana (but that doesn't really matter, since only mages have more mana than Paladins... and Imps will add to it), but it will only cost you 0.5 initiative. And if you have Expert Sorcery, you'll only move 0.2 on the initiative track and you'll have time to cast Mass Haste or Mass Righteous Might (and by the way, you'll add...). As for the battle to the last... well, that's good for dungeon dwellers; they can take down 1-2 angels or dragons with a Strygoi... and Archdevils: they can summon (if they haven't already) more Lords... IMHO, it's better to have readiness: imagine 10 Paladins, 30 knights attacking: and they attack them first, then there's a 30% chance that Hellfire will hit... and if you have Cold Steel or Fiery Wrath (or both ;) ), you'll definitely take down 7 of them, and the rest depends on probability...
