Arnie's post was an additional prompt.
I believe it's not important, ,so don't worry about not being able to repeat 2 stars,
Though on several occasions it looked like I was going to succeed and get 3 stars, there were times I also failed miserably at repeating 2.
After Arnie's addition, I went back to check and read through the whole thread, doing so might prove beneficial to others.
Most , but not all, are recommending Viva, and apart from not adding anything to Health except through armoury. nothing else is consistant, suggesting there is no ideal set up.Unless there really is, and it's a secret !
I kept note of all runs and gloom type, and from run 34, how much health was lost in each room.
Though I started with a different set up, and changed it for some of the attempts, I dropped the use of several items of Beowulf gear, but never got round to returning to Ghostly Veil.
Here's what my champion finished with.
Not got round to repeats or trying Viva.
I could be wrong,may have since updated,but I believe at one time it was with the rewards for 1 star.
I got the headband in a room chest, but unless you drop lucky (I did the boots) chances are you already have something at least as good, if not better.
Floor 10, node 4 ,still only 2 stars, ran into a chest second room.5 boxes, last one Beowulf's Headband, ( on checking, doesn't seem there's much improvement on Ghostly Veil) so will see if it helps any now.
Weirdly, cleared 20 rooms finishing with 1 health after several rounds against a very strong opponent at this mark.
Just did only 19 rooms wearing the headband.
