Silence is Golden

Missable because it depends on defusing the raid through dialogue rather than letting it kick off - and the speech checks lean on stats you may not have built. Go in with your Speech/Charisma boosted (right clothes, a Bard's Brew if you have one) and pick the de-escalating options. Save before the key conversation so a failed check isn't fatal; if it's already gone wrong, the permanent quest-start save is your reset.
