You are level 12 holding xp for 13 for a few days so you can build up a few runs of the Sands walkups trying to make the new xp changes work for us and you loot a junk cursed ring. Looking at your gear list you are still wearing your bta lvl 7 greater false item ring aka time to level up.
Once you add the GFL it is now level 13 so you have a few days to think things over, what is the play?
You have a yellow and a colorless to work with. I will stick an image of captan smexy pants so you can’t skip down to my answer too easily.
The answer is fairly simple I think. Fear Immunity is huge. Sure we have fairly good will saves, but as we have FoM as a spell; fear effects and greater command are about the only spells that we are worried about. And I don’t know about you but if I can fail a will save I will. And then with Vitality as an option we might as well hit it and make this a huge Hp ring.
Other allowed but less good answers include a combination of the above and Blindness immunity and a +7 skill like heal or spell power. But again I think the above is the right play.
