Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

As the title. Do the blackguard aura and frightful presence for example stack? (or rather, work at all. I've tried, but couldn't really see any results from either)

frightful presence is not an aura - has to be cast over and over ...

No idea if it stacks.

Aaaah, thanks for clearing that up. I thought it was an aura. That explains why it didn't work
