Ah yeah. I actually didn't really understand understand what you were talking about with that. No idea who Gibblebog is. Should have asked for clarification before.
Gibblebog is that Gnomish leader of raiders around Dark Crypt.
Ok few another examples:
When you try to persuate Lump (i believe?), leader of Ogres to fight for you.
When you try to intimidate Kithrak, leader of Githyanki patrol.
Eeeeeh ... that would be about it ...
Unless you want to count every other NPC (wich would mean that examples are all of them) on wich you can use any Charisma roll, and then you can simply walk far away to let them cool down.
Example of such behaviour would be Leader of Zhentarims ... you can persuate her with Friends, then walk back to previous room, cancel your concentration, walk back and she is still friendly. Or at least she was last time i was bu... i mean testing it.
