| The demon hand kind of loses it's coolness when you see that the npc chick he runs with can do the exact same moves without one.
The designer in one IGN's video said he dies from the enemies darkness (or whatever that Venom looking crap is) but he's able to touch them with his demon hand -- so when he fights demons with the darkness he only uses his demon hand. The video I watched on IGN showed him stepping on the darkness while fighting the enemy and he didn't die...at least from that video it seems like they want you to ignore that. |
