Hi all,
I'm going to playing in a campaign soon as an undead anti paladin. (the whole party is undead). The short version of the backstory is i'm undead with my soul tethered to my body as my shadow. With the soul being my fiendish companion. No the shadow demon fits great into this flavour (we are 12th level) but next level I swap for a new one next level.
Now here is where the issue comes up. My only Bebelith or a vrock which really doesn't fit. So I'm wondering if advancing the shadow demon is a possibility? or if anyone has tried that for the companion (advance it to cr9 or 10 where the next summon monsters sit). My only issue is the rules for advancing HD seem boring (always has the same abilities) but the rules for adding class levels seem really powerful... ( http://www.d20pfsrd.com/bestiary/rules-for-monsters/monster-advancement) with the stat buffs and all. and With the monsters that like the shadow demon that has higher CL for spell likes than HD I'm not sure how to advance that.
My GM and I are trying to figure something out but I would love to hear some opinions or experiences with someone who has tried this?
