How exactly does "weighted dice" work? The rules on the card are not very clear.

If you land on a space and are draw a "trap door" card, upon landing on the Dungen entrance, do you draw another card?

You use the Weighted Dice instead of rolling the die as normal for either a move or attack roll. You then pick whichever result you want as if you had rolled it.

If you fall through a Trap Door you encounter the space you land on.
