Core rule
Damage dice
1d8 means one eight-sided die. 2d6 means adding the results of two six-sided dice.
For 1d8 + 3, add three to the die result. With no other effects, the damage ranges from 4 to 11.
A weapon’s damage range is a starting point for damage on a hit. Resistance and other effects can change what the enemy actually takes.
