Did you get the scrolls from Dantillion's Residence(?) in the Murmur Woods village? I checked a guide, and it said casting the spell manually will not work.

Are you trying to cast the scrolls manually, or are you clicking on the statutes while the scroll is in the active character's inventory? If you haven't tried just clicking on them (don't try to manually use a scroll on them), then try that. Make sure the active character has a scroll in their inventory when you click, just to be sure.

As an additional note: When you rescue Cauri. make sure to ask about the promotion before closing the conversation. Is Blazen the one holding Ebonest (either in hand or in inventory)?

Thanks for the help. I'd never have thought of something as obvious as simply clicking on the statue rather than actually using the spell scroll. The Knight thing was strange. What had happened was that Ol' Charels had already gone to Raven Shore. So the guy in the chair was somebody else. HE promoted everyone when we went back to Ravenshore

Ah. Yep, you have to go where Charles is actually located in order to get the promotion.

The dragon faction leader is also the one who promotes Dragons, so the same issue applies (for Dragons) if you side with the dragons.
