Heh, yeah that too. I only ever invested 1 point in that talent, as the payoff is so low. Only worth it to advance to the higher skills. It's not a terrible amount of damage, but once every 20 turns to hit a single mob is just not worth it.
- Once every 20 turns is not the same as once every 20 turns of combat. If you're walking around much between fights, for example, it provides a delightful chaser for your Blindside alpha strike
- it's will-dependent.
- it takes no actions. It's just free damage on top of whatever else you're doing.
- it's the only thing you have other than the life drain aura that can reliably damage things that you can't reliably hit with a melee weapon.
Or, to put it another way, I've gotten it on my non-rampage Cursed, and been quite happy with it. I suppose if I was intending to max the rampage tree, I might find it not worth the points, but if you have some points to spare and are going to be maxxing your will anyway, it's a solid place to put them.
