Pffffhahaha, are you serious? You think there are less than 6 enchanted helmets in the game? The enchantment doesn't even have to be amazing. A permanent +stat and +skill beats +20% dmg when the enemy is under 15% health any day.
No, that's not what I was implying I'd put money on it there's lots more, but there not all going to be useful for every character build. Where'd you get the under 15% health from by the way you're the only source I've heard that from???
I'd still argue that even a small bonus all the time is better than a medium sized bonus under specific circumstances.
The 15% come straight from the Death Godlikes ability description during character creation as of v480.
Wow how did I miss that, it should really say that on the talent screen as well, thanks That amount does make it a bit crappy then. A Barbarian with 2 weapons and carnage might still be ok for it though, not many other classes I'm guessing depends how many enemies have over 100 endurance.
