Because a few ppl have asked about my house rule, “I Know a Guy:” it’s meant to create that moment in ESB when Han decides he can go to Lando for help, but isn’t 100% sure how Lando will actually receive him: 1/ #dnd — David Nett (@davidnett) March 27, 2018

In any situation (where it makes sense), a PC can declare “I know a guy,” and then quickly sketch that NPC & the relationship. Fewer details are usually better – that leaves room for the DM & PCs to play. 2/ #dnd Upon declaration, the NPC exists. Then, when the PCs try to interact w the NPC, the player who created that NPC makes a Charisma roll to see how the NPC reacts. Depending upon the situation, the DM may decide advantage/disadvantage applies. 3/ #dnd — David Nett (@davidnett) March 27, 2018

I’ve found this simple and very loose mechanic invites players to create critical NPCs AND continue developing (revealing) backstory as they play. Now it belongs to the world (if you wanna try it). 4/4 #dnd — David Nett (@davidnett) March 27, 2018

Saw the "i know a guy" house rule again by @davidnett. Thinking of implimenting it with uses equal to the pc's charisma modifier, minimum one. pic.twitter.com/X6lnoa3QnW — ɟɟnʇs ᗡ⅋ᗡ ǝʞɐɯ oʇ sǝıɹ⊥ ˙ᴚ˙Ԁ (@CowboyCentaur) December 23, 2018

Genius! Love how this house rule brings action and uncertainty to the game. https://t.co/iHtOSiilEi — Mike Mearls (@mikemearls) December 24, 2018
