Gambling in 5th Edition D&D 2 of 7: Dice

Dice

Winning at dice can come down to either straight luck, or to your proficiency at cheating. Lastly, in some games like Yahtzee it depends on both luck and your choices. This sample dice game will be based on both of those things as well as cheating. Your dice Proficiency is essentially the luck portion of this. This is an example of a full evening's gambling, not a single throw of the dice. Each dice session lasts a full four hours and does not count as rest. There may be a limit on your initial investment based on those you are gambling against.

Copper +0 DC
Silver +5 DC
