Ok - I apologise in advance if I'm missing something here but I would really appreciate it if someone could help me with this!
I've watched the videos, read the guides etc. and the consensus seems to be that you should keep the boss and the doom guard on the pit lord by using the gateways to drop threat. However, no matter how many times I use the gateways, my threat is not dropping. When the Doom Guard comes out of the portal, I instantly use the pit lords attacks on it and use the gateway but to no avail - I had to use soulshatter in the end!
Can someone please tell me if I'm doing something stupid here - I'm getting to grips with the other mechanics but I can't seem to succeed whilst my threat remains high.
Thanks in advance!
