A '''damage source''' | A '''damage source''' is an attack or other effect that directly deals damage to one or more targets. Examples include striking a target with a [[Weapons|weapon]], many [[spells]], or thrown items such as an {{SmItemIcon|Alchemist's Fire}}. Damage sources usually require the use of an [[action]] (e.g. throwing an object such as a [[Grenades|grenade]]), [[bonus action]] (e.g. making an attack with your offhand weapon while dual wielding) or [[reaction]] (e.g. the {{SAI|Hellish Rebuke}} spell). | ||
A '''damage rider''' is something which adds | A '''damage rider''' is something which adds to the damage dealt by a source. A rider cannot deal its damage independently - there must be an applicable damage source for it to "ride". Examples of damage riders include the {{SAI|Hex}} spell adding damage to the damage from a Warlock's {{SAI|Eldritch Blast}} or weapon attacks, [[coatings]] applied to weapons providing additional damage to a weapon attack, a 6th level {{Class|Draconic Bloodline}} applying their [[Elemental Affinity: Damage|elemental affinity]] to a spell of the appropriate [[Damage Types|damage type]], or a raging {{Class|Barbarian|25}} adding bonus rage damage to their weapon attacks. Many damage riders are gained from passive features or other kinds of buffs. Any eligible damage riders from a damaging effect will be applied to a damage source which is a part of that damaging effect. | ||

There are some damage riders which defy the typical trends described above. They still must "ride along" with a damage source in order to be applied, but when the damage is calculated they are treated as damage sources instead of damage riders. This means that these "'''damage riders which are treated as damage sources'''" can then cause normal damage riders to be applied once again as part of the same ability (e.g. attack or spell) which caused the damage. | There are some damage riders which defy the typical trends described above.
