D&D 5E Timing Question: Uncanny Dodge vs Open Hand Technique

[Stalker0]

Uncanny Dodge is a reaction to half the damage of an attack.

Open Hand Technique allows you on a hit to prevent the target from taking reactions.


The Question: If an Open Hand Attack hits, can the opponent use uncanny dodge to half the damage....or would the technique kick in first and prevent the reaction?

 

[Kobold Stew]

The monk hits and chooses which effect impacts the target. If they choose the third bullet point (no reactions), then the target cannot use Uncanny Dodge.

That seems straightforward.

Unfortunatly it can't. When an Open Hand Technique Monk hits a Rogue with Flurry of Blows and choose to prevent reactions, the Rogue can't take reactions to halve damage or anything else until the end of it's next turn.
