Add the immunities listed and SR, too.
I'll agree to standard blindsight and the fear aura, too.
Updating Maturing Baatorian Working Draft.
We need a value for the spell resistance, which was originally a rather unimpressive 15% Magic Resistance. Shade's SR guidelines would give it either CR+12 (for being a Devil) or CR+4 (for having 15% MR).
Maybe split the difference and give it somewhere around CR +8? That'd probably put it somewhere around Spell Resistance 12.
Hmm, I like SR 13 for them. Would that be OK by you?
Rather than standard devil characteristics, do baatorians have standard characteristics?
As far as I know the Maturing Baatorian in that Infinite Staircase adventure is the only published stats for a Baatorian. I believe there are a few mentions of their existence in Planescape sources but nothing mechanical that covers details such as standard abilities. They are a very obscure beings.
