# Do I add an enchantment bonus to sneak attack damage?

I was looking over the Sneak Attack entries in D&D 4th Edition, as I am playing a rogue in a Planescape campaign. Anywho, I was wondering if a Short Sword +2 would add it's enhancement bonus to Sneak Attack damage, as well as the AB and the normal damage roll.

No.

Sneak attack is extra damage added to the attack. It's part of the attack roll where the enhancement bonus is already added, you don't get to add it again.

So you should have:

 Attack: 2 (ENH) + Dex + 1/2 lev + 2 (CA) + x (other mods)
Damage: 2 (ENH) + Dex + Sneak Attack + x (other mods)


As a commenter points out, because this damage is part of the attack roll, it's maxed on a critical hit as well (this also goes for other striker damage like the warlock's curse, and ranger's quarry dice).

I'd add to this a note that because it's part of the attack roll, it benefits from a critical hit, just as other damage dice do- so a heroic Rogue would max out those 2d6. – JLan Dec 4 '13 at 19:13
