Aura of glory the spell is not adding any charisma to the caster or any allies currently.
Its only supposed to heal nearby allies. Also did you have eagles splendor up at the time? I'm pretty sure they're SUPPOSED to stack, but it may not have due to some odd script preventing it.
I've noticed this, If eagles in on, the AoG does not add +4cha. Essentially making it a fairly redundant spell. Was this altered on purpose?
No, if it's not working then it's a bug. It should stack.
I did have eagle's splendor up but as Howland said it should stack.
Relinquish posted something similar a while back with the same issue but he mentions this:
QuoteThe spell doesn't give the +4 charisma bonus promised by it's description, it does however seem to give the fear saves and d4 healing.
Accnt: Efu_Dimitri
Character: Dimitri Sudnik
This still exists as a bug.
I've used this from an item with aura of glory and have had the same experiences; no cha bonus, but fear save bonuses and hp granted.
I didn't have eagle's splendor up at any of the times, either.
