The Extended Banter component adds numerous banters between the Bioware NPCs, humorous, serious or otherwise. Your companions are people too - surely they deserve more talking time! This release includes the following banters for SoA:
Aerie/pre-test Anomen [1]
Aerie/Sir Anomen [1]
Aerie/Mazzy [8]
Aerie/Minsc [6]
Aerie/Valygar [1]
Cernd/Imoen [1]
Edwin/Viconia [5]
Imoen/Jaheira [2]
Haer'Dalis/Imoen [1]
Imoen/Viconia [3]
Jaheira/Viconia [8]
Keldorn/Valygar [2]
Korgan/Viconia [2]
Minsc/Viconia [1]
I would suggest more banters involving Cernd and Haer'Dalis. I do not know if this is already in progress, however.
The Extended Minsc/Aerie Interaction ToB component includes two banters for Aerie and Minsc in Throne of Bhaal.
The Conflict Revisions component includes conflict revisions, which allow the PC to intervene before NPC disagreements turn ugly. It revises the following conflicts:
Edwin/Keldorn
Edwin/Minsc
Edwin/Valygar
Keldorn/Viconia
How about the Korgan/Aerie conflict? Did she not leave the party if the protagonist does not respect her wishes and send Korgan away? Would that count as a "conflict", or is it mainly about conflicts involving bloodshed?
