In order to render gold and silver dice somewhat more useful during combat for the overlord, has anyone thought about the following:
During combat, the Overlord can convert two surges to 1 damage instead of gaining 1 threat.
It is extremly frustrating for the Overlord to throw gold or siver dices at high campaign levels and end up with practically no damage when the dice rolls result in many surges. Of course the tradeoff is that you don't get the threat, so the decision still needs to be carefully considered.
