[RPG] Does the Monk forgo damage when using Stunning Strike

class-featurecombat-maneuverdnd-5emonk

In the 5e Player's Handbook the following about the Monk's Stunning Strike is written:

"When you hit another creature with a melee weapon attack, you can
spend 1 ki point to attempt a stunning strike."

Is the rule to be interpreted as replacing the attack damage with the stunned condition, or does the stunned condition add to the damage inflicted by the attack?

Best Answer

You deal damage

PHB page 194:

Resolve the attack. You make the attack roll. On a hit, you roll damage, unless the particular attack has rules that specify otherwise. Some attacks cause special effects in addition to or instead of damage.

Stunning strike does not say you do not do damage. PHB page 79:

Starting at 5th level, you can interfere with the flow of ki in an opponent's body. When you hit another creature with a melee weapon Attack, you can spend 1 ki point to attempt a stunning strike. The target must succeed on a Constitution saving throw or be Stunned until the end of your next turn.
