"I Know A Guy...": When facing a difficult problem, a PC can declare "I know a guy..." and invent a helpful NPC which the PCs can visit for aid in their current situation. When the PCs try to interact with the NPC, the player who created them makes a Charisma check to see how the NPC reacts. A PC may use this ability a number of times equal to their intelligence or charisma modifier (minimum once).

Potion Quaffing: Potions can be drank on a bonus actions, but feeding a potion to someone else requires a full action.
