@valkebus - But EW already have a great early level high damage against unarmored weapon - The Laser RCW. Why mess with the Incinerator when I could use that?
@Madocmayhem - I like the idea of extra limb damage. I will have to test that out in a mod. Also, how about giving explosives in auto knockdown?
Actually this is a good idea, I'm not sure about a 100% chance though as it would ruin combat for me personally.
I would go for it on a critical strike to make up for no extra damage, and would make a sneak attack seem more realistic.
I.e get hit with an unseen frag you're not going to stay up for long, whether the shock makes you cover or the blast wave knocks you down.
I did this a while back on sledge hammer and powerfist for FO3.
Or have the KO on a head / torso cripple.
