Stam Sorc's already get minor berserk from DD, I personally prefer to swap out Camo Hunter for spell crit pots to get my major prophecy because it carries to back bar where your heals are (stacking with minor prophecy for +18% crit). That free slot can go a longgggg way. Quick Cloak for damage/mitigation. Wield Soul for a dot execute and major Vitality. Soul Burst for an aoe dot execute and minor courage or intellect+endurance. If you don't like mag crit pots, you can slot DW Traveling Knife with multi target + sorc script + major prophecy for a really strong spammable that hits 3 times. 1 time more than Rending Slashes to tripple dip the damage done sets. Lots of options :)
Pretty much both of them. crystal weapon into light attack+rending. Most the time, as i can see, he's using it like that. But first of all he's trying to get enemy with rending, so it can begin stacking appetite+slow+dot.
when you are dual wielding, does one attack count as two light attacks for triggering crystal weapons (8500+3600)? Basically my question is how often do you rebuff crystal weapon?
No. You get 7 seconds of hard cc immunity, includes stuns, fears, and interrupts. So you know after you break free from a stun, you have free reign to cast dark deal to your hearts content. This does not apply to like capture the flag, you can continuously interrupt those players indefinitely or else the game mode wouldn't work.
