The graveyard is really hard. Grind them down near the entrance if you can. Trying to just rush it at level 50 is suicide.

I have just done the graveyard at Level 49 - and found it fairly easy ,
not even needed any bonemeal or lesser shadow rings

Key to it were in my opinion

A high level of defense and the taunt skill

I am currently in a cave 'On the Way to Brimhaven' with a Radiant Guardian that I can't hit. My 'arms are held back by an enormous force'. This seems like a quest but I can't find it.
Another website says this is part of the quest 'An Involuntary Carrier' and the start of that quest can be found 'on the road from Loneford to Brimhaven'. If Brimhaven doesn't exist yet, how does anyone know where the road is between Loneford and Brimhaven?
So confused.

When you enter the cave, go in the other direction first. There's someone you need to talk to.
