Hey @JeremyECrawford here's a weird question
If a PC is in melee with an enemy, the enemy knocks them back, does that count as the enemy moving out of threat re: opportunity attacks? Can a PC make, say, a reaction to use a whip to grab onto the enemy who knocks PC off a cliff?

You trigger an opportunity attack when you leave an enemy’s reach. But you don’t trigger one if you teleport or if something moves you without using your action, reaction, or movement. The Player’s Handbook goes into more detail on this. #DnD https://t.co/xrVwKrmN4B

Yeah, but the question was about the pushing character triggering an AoO from the pushed, not the other way around My answer also applies in that situation.

When you push someone away, the other person is moving, not you. #DnD https://t.co/xrVwKrEotb

My interpretation is that attacks of opportunity are only triggered by active movement from the person moving on their turn. Forced movement, ie a push, pull or knockback does not apply – otherwise you could just take advantage of the AoO feature constantly and trivialise combat

You can trigger an opportunity attack on anyone’s turn, not just your own. But you must use your action, reaction, or movement to trigger it. #DnD https://t.co/SQDgueFog8

How does that compare to the effect of Thunderwave which 'just happens', but it is the other person moving, not the caster, yet does not provoke an Attack of Opportunity? #DnD @JeremyECrawford

An effect like thunderwave doesn’t cause the moved creature to trigger an opportunity attack since it doesn’t use their action, reaction, or movement to propel them. (Thunderwave is mentioned in the rule on opportunity attacks in the PH.) #DnD https://t.co/vFAOXrqXQM

In other words, a creature needs to use their movement to trigger AoOs, they can't be forcefully pushed/pulled or any other effect that would move them against their will.

You can trigger an opportunity attack when you’re moved against your will, but only if your move uses your action, reaction, or movement. A number of charm and fear effects do this. #DnD https://t.co/aP7DmvCCdC

The dissonant whispers spell in the Player’s Handbook is an example of an effect that moves you against your will and can cause you to trigger an opportunity attack, because it uses your reaction to move you. #DnD https://t.co/SYYy4EWYHp

So Warlock's Repelling Blast Invocation won't cause an opportunity attack? I was just debating this last night.

Repelling Blast doesn’t use the target’s action, reaction, or movement to push the target, so that move doesn’t cause the target to provoke an opportunity attack. #DnD https://t.co/RHjXPVssDM
