i'm DM to a 4th edition campaign. Been a DM for about 13 years through 2nd and 4th edition and never had to deal with this.
We have a kind of new player into the party, a rogue from PHB1. During combat he kept asking if he could attack the eye of the enemy (Young Blue Dragon) to disable him, or just rip off one of the wings.
Now i know we're in combat, and to get hit in the eye you just need to be very careless or the attacker has to come completely by surprise to achieve something like this.
I can't seem to fond any rule regarding this issue.
The rogue just accepted that he couldn't attack the dragon's eye reluctantly.
Now my question is: Is there any source material addressing this? For now i made a table rule:
If you want to attack a localized spot, the defender cannot know of your existence (invisibility, teleport into battle, etc).
The usual bonus apply, (combat advantage)
If you miss the attack, the defender gets a free opportunity attack with +2 power bonus (aiming and focusing in the attack would be something like range attack, hence combat advantage). This is to prevent possible abuse.
I want to know if this looks like a reasonable rule to deal with this kind of attacks. Or if someone here has more ideas.
