- cards only needs more Prestige to be activate but still give the same amount of Prestige when roll the die
- Add another die (I don't know how since I am using symbols and give more chances and combinations and I don't want that)
One idea might be to allow the use of a different die. For example, have another d6 that has the same four symbols plus two wild symbols. A wild could be used as any symbol the player chooses, so it allows for some strategic choice.
Alternatively, if you want to go with the two dice idea, you could allow the player to roll both and then choose which of the two symbols to use. If the player rolls doubles of the same symbol, you could boost the result somehow (e.g. say +2 to the result, if doubling would be too powerful). Or you could even have powerful cards that require TWO symbols to activate.
