Mythic Battles: Pantheon – Battle Dice

From publisher: Now, you can have some more dice, and we even give you a choice. You can choose between another set of 10 Battle Dice, the ones provided in the base box, or 10 Classic Dice, for those who prefer numbers to sword symbols. As a reminder, these special six sided dice are numbered from 1 to 5, the sixth face being blank. The 5 is the "explosive" side, hence the special symbol for the Battle Dice. Each time you get a 5, you can reroll it and add the new result to 5. This allows you to get target numbers higher than 5.
