Healin Signet Recharge

I've noticed a few times while farming Desert Griffins, my healing signet takes a significantly longer time to recharge & I end up dying before I’m able to use it again. I’ve looked in the upper left hand corner of my screen to see if I had any hexes or conditions on me, but nothing. Also, it happens almost every time I attempt to farm the Mountain Trolls in the Ice Cave north of Droks. I thought it was maybe because of my Doylak Signet, but it only happens at certain times. Just wondering if someone could explain what causes this. Thanks.

Desert Griffons are easy....They are called Rockshot Devourers..and its called Distracting Shot.

The BANE of Griffon farmers.

the trolls are using Disrupting Chop, which does much the same as the rockshot's Distracting Shot... which is to add 20s to the re-use timer

You can draw the attack out harmlessly by covering the sig with a stance, some other skill used as 'bait', or by starting the sig and hitting the escape key quickly to abort it before the interrupt lands... as always, practice makes perfect

Trolls also do disrupting chop, adds 20sec to the recharge. If you're taking signet and relying on it to stay alive, make sure to do it under bonettis or <insert other nowhere near as good defense stance here> to minimise the risk of it being messed up.
