In the Isolated corruption card there is the text "you may not consult with characters or trade with other heroes." Now I have read the rules and looked a little bit on the forums and google but I cannot find the player trade rules. Untill now we have had the belief that players cannot trade, but since they obviously can what is the rules on player trade or is there any rules?
Player trading

may freely trade favor, Item cards, and Quests with each
other (excluding Starting and Advanced Quests)." (p. 24)
