This would be so cool. Negotiations are a blast in SMT and I would love to have them in Baldur's Gate 3.

Negotiations would alleviate the issue of failing the skill check in the conversation and they would help players complete pacifist runs.

As a Minimum, I'm picturing:
If player tried to persuade/intimidate to avoid combat.
AND
enough enemies are dead, unconscious, prone, etc.
AND
If the leader is still alive and about to be killed/knocked out (successful roll)
THEN
Leader will try to resume the conversation as if the player had succeeded the skill check.

The player will be given the option to show mercy or kill.

I would love to be able to demand ransoms, etc. But that is a lot of additional voice acted dialogue. If Larian is willing to do it, I'm willing to have it grin
