Silas Sparrowbrooth's conversation for the Mongrelwoods almshouse quest has a Persuade check (And intimidate, but I didn't try that one). It has a DC of 0, which seems wrong.
Yeah, would need to know where to find this NPC. Please try to always provide information with assumption that someone does not know where or what you are talking about, as it's a very large project.
Ring 99 - Ticker Square - The Open Door Inn
He should be behind the counter.
Go figure, I was thinking totally different NPC. Shows how well I remember names.
Fixed I hope.
