In Season of Factions’ Favor, traders work differently than in Mummy’s Mask, in the following ways.
• When you are rewarded with a trader, instead of checking it off on the Bazaar card, record it on your Chronicle sheet.
• You do not visit traders after winning a scenario. Instead, at the start of each scenario in this Adventure Path, before setting out the locations, you may visit 1 trader you have recorded on your Chronicle sheet.
• Pay the trade cost with the usual number and type of cards from your deck, but instead of putting those cards in the box, put 1 in to your deck box and bury any others.
• At the end of the scenario, return the card you traded for to the game box, and put the card you returned to your deck box back into your deck.
For example, to pay the trade cost to a trader offering spells at a cost of 2 boons, put 1 of those boons into your deck box, bury the other boon, then add the spell to your deck. At the end of the scenario, return the spell to the game box and put the first boon back in your deck.
