When does Undead flee, when Turned?

[Cahina]

Hello Y'all,

So, in our adventure today. our cleric was surprised surrounded by 8 zombies. how it happened, well it did. anyways, our cleric decided that the best route was that turning undead would be the best since, me being a ranger, could just pick them off with my bow. So the cleric does his cleric thing, and Turns Undead. he manages to turn 5 of them. Now, since the cleric is doing the turning, do the undead flee their movement speed immediately, or do they flee on their turn? It made the most since to me, for this to have an immediate effect and the undead would have to flee, which would after cause a bunch of Attacks of Opportunity.

So, anyways, i guess my main question is. When do Targets of Turn "monster" flee? on the clerics turn, or the flee'er's turn?

Thank you and have a great day.

On their turn.

If they go before the cleric turns them, making them flee on the cleric's turn gives them an extra action.

They begin fleeing on their next turn.

As always TOZ you provide much better answers to me even when we agree.

Actually, I accidentally previewed my response and saw you had already posted the same thing, and thus expanded my answer. :)
