Drained as a Skeleton in FotRP

I am currently playing a skeleton cleric of Gorum in Fists of the Ruby Phoenix. In the pre-qualifier part of the AP, I got drained 3 on day 1 of the 3 day tournament. Because of the nature of the AP, this drained condition will likely be affecting me for the next 8-10 sessions, which sucks. I am a 13th level cleric now, and have just gotten my first rest. Is there any spell on the divine list I can prepare or any item I can purchase to help deal with the drained effect? The typical go to is sound body since the remaster, but that has the vitality and healing traits.
