# Deadly

**Source** [_Core Rulebook pg. 282_](https://2e.aonprd.com/Sources.aspx?ID=1) [4.0](https://2e.aonprd.com/Sources.aspx?ID=1)  
On a critical hit, the weapon adds a weapon damage die of the listed size. Roll this after doubling the weapon's damage. This increases to two dice if the weapon has a _greater striking rune_ and three dice if the weapon has a _major striking rune_. For instance, a [rapier](https://2e.aonprd.com/Weapons.aspx?ID=36) with a _greater striking rune_ deals 2d8 extra piercing damage on a critical hit. An ability that changes the size of the weapon's normal damage dice doesn't change the size of its deadly die.
