[sblock=ooc]Oops, did we trigger two encounters at once? Geeze
Regarding Howl of Fury, I'm actually of the other opinion, that it does not trigger the vulnerability. Close or area
attacks trigger the vulnerability. This power is not a close attack, and in fact the follow-on damage in the blast 3 area isn't really an attack at all, so it's subject to neither the resistance nor the vulnerability. "close blast 3" is just used to describe the area that is subject to the follow-on damage, it doesn't make it a close attack.
It'd be the same for a power like Cleave, though the attack you roll to hit with is a melee attack (and thus triggers the resistance), the extra damage handed out to an adjacent enemy is not an attack (no to-hit roll), and would be applied without any modifications. Similarly Divine Challenge, though I believe you target it as a close burst, if the radiant damage triggers it goes through unmodified, because that part is not an attack. That's the way I play it in my face-to-face game.
It's definitely the case that the primary target of the attack would take half damage since it is a melee attack power, I don't think there's any doubt about that.
Of course it's to our advantage if Kane can use it to hit the vulnerability, so I'm not going to argue too hard about it.
I will post a move later tonight. Have to decide whether to use Resist Energy now or try to save it when others are adjacent.[/sblock]
