Damage Dice

Each weapon lists the damage die used for its damage roll. Improved versions of a weapon can deal multiple dice of damage. Counting Damage Dice Effects based on a weapon's number of damage dice include only the weapon's damage die. They don't count extra dice from abilities, critical specialization effects, weapon fusions, weapon traits, or the like. Increasing Die Size When an effect calls on you to increase the size of your weapon damage dice, instead of using its normal weapon damage dice, use the next larger die, as listed below (so if you were using a d4, you'd use a d6, and so on). If you are already using a d12, the size is already at its maximum. You can't increase your weapon damage die size more than once. 1d4 » 1d6 » 1d8 » 1d10 » 1d12
