Has anyone worked on rules for playing multiple cards together? I'm thinking of combos where the name of the card suggests a linkage, things like Sage and Sage's Journal. By itself, Sage's Journal adds 1d4, together they might add 1d4+2.
The mechanic is similar to multiple pieces of armor. It seems there are several Ally/Item combinations that should reinforce each other, such as Burglar/Masterwork Tools. These are already additive on the Disable check, but playing both could give the item another die, or make the die d6 instead of d4.
And if anyone can think of a way to make Shopkeeper's Daughter and Large Chest work together, please let me know.
