On another note something occurred to me which has me worried. Minthara is apparently a vengeance paladin, or at least she used a vengeance paladin ability. I really hope Larian don't just make that oath the "evil" oath.
Since she doesn't have a tadpole Minthara seems to voluntarily serve the Absolute, maybe she is an outcast Drow and wants to get revenge on Lolth that way? Hence Paladin Oath of Vengeance?
On the other hand, I rediscovered another older thread
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=835054#Post835054 with a reply of mine that I had already forgotten about:
Yes, it is very strange with the Oathbreaker. It feels like an armored Warlock. Or in other words, if there is a mulitclassed Oathbreaker / Warlock later on, he feels like he has two Pact creatures he is bonded with. I don't know what to make of it.
Matthew 6:24 No one can serve two masters...

Are Warlock Patrons automatically all evil? The Raven Queen is rather neutral. Even Jahreira is neutral, but is often classified as a force for good especially in connection with the Harpers, if I look at the classification of the companions in other threads. This paladin deity & alignment story is quite complicated.
