Hello fellow Gielinorians!
I got a simple question for you all that I would like to get answered: How would I best go around obtaining my final Marmaros and Thok Letter (Part 4) from Dungeoneering? I got all but this letter unlocked, and am currently level 118. I would prefer to get it before I hit the maximum level. Do I need to keep redoing the floors around the 15-25 mark, as I have heard from a few sources? Do those need to be of any certain complexity? Any certain size to maximize my chances?
All and any help is very much appreciated.
