Necro in lower guk

[Castamere]

I never did a whole lot of guk on live so I thought I would take my 51 necro their to learn a bit of the zone. IVU down to to the frenzy spawn and decided to try root rotting some of the blue cons *outside* of the spawn room. The main problem I'm having is paralyzing earth breaking so often. That combined with the tight spaces and not a lot of room for a runway made for some pretty painful breaks.

So after thinking about it I have a couple ideas for a new approach and hopefully someone can share their experiences as well.

My first idea was to try using screaming terror as apposed to immediately casting PE again on breaks. But now that
I'm looking at it, ST has a longer cast time so that option seems out.

So i'm wondering if perhaps a different root spell would be a better option. For instance, hungry earth. Only works on undead which is fine in this case and last for 8 ticks. The wiki doesn't say that it breaks randomly but that could have been left out I suppose. If that's true, I would love a consistent 8 ticks of root if I could count on it. Seems to good to be true.

Besides that I'm kind of at a loss. Wait for 52 and manaskin?

At work can't test myself. Thanks!
