sustain power charge with hege's era

Hey

what is the best way to sustain power charge while using hege's era ?
do i have to get pc on crit ?
a good rolled flask would do the job ?

Struggling on this, please suggest..

regards,
ouis

Whirling barrier (10% on block) + Blunt trauma (10% on KB) would be probably enough but haven´t tried myself.

Herald of ice + curse on hit + AM curse or CWDT + AM curse

Leap + faster attack + fortify + PCOC

Skyforth ...

Probably some more

blasphemy + assassins mark + ice golem, I sustained my charges without any issues except for hexproof

Sweep might be enough for clearing packs, but well... you're using sweep.
Otherwise, just you everyday sustain - assassin's marks, Charge on Crit and so on...

i guess i have to trade my empower for a pcoc then..
playing frostblade CoC articbreath, and staff nodes + rolled flask arent enough :/

knockback for flask duration

Isn't it awesome how there's just no good way to sustain power charges on most any build that can't accommodate one of a small handful of super specialized pieces of gear, a wonky and unreliable CoH set-up, or sacrificing links for a PCoC gem that needs charges in order to sustain charges?

Frenzies are simple, reliable, helpful.

Endurance is less of all three, but still has a decentish method of sustaining in Enduring Cry and a few options for building.

But Powers? Power charges suck on all counts unless you're fortunate enough to be an Assassin, and even those guys have issues if you try and cap out your crit chance - WHICH IS WHAT POWER CHARGES ARE FOR. UGH.

Isn't it about time we got a cleaner method of working up/keeping power charges?
