So, what's your ruling in this situation:
Situation: Enemy fighter, 20' away from the PC, armed with a javelin and a longsword. He has the extra attack ability for 2 attacks per attack action.
Readied action: If the enemy fighter moves next to me, I will move away
Creature's turn: The enemy fighter uses his attack action and throws the javelin at the PC. He then closes to the PC, moving next to the PC. He then uses his second attack to make a longsword attack on the PC. He then continues his movement away from the PC.
What I would rule at my table isn't the question being asked here, just like how you would rule at your table isn't. The question is more like what's the official intent for how this resolves. You claim to know intent, but you can't possibly prove that you do based on the posts you've given so far. You're not a dev. Also:
This clearly interrupts in between multiple attacks within an attack action. The given example, presented without caveat as a 100% valid trigger, shows that this is so. Now, you, as DM, may choose to allow or not allow a trigger as reasonable, and you may choose to never allow for a trigger to be stated that could possibly interrupt between attacks, but you're going to have to make sure that you're doing that at the 'determine trigger' step, because after that the rules say nothing about not interrupting between attacks and instead say that if the trigger occurs, you interrupt immediately after.
No it doesn't.
To be fair, no one here is arguing that point. We're all very clear on that.
No we're not since it's been claimed in this very thread multiple times that a readied dispel could interrupt Eldritch Blast, an instantaneous spell. This is only one claim that's been made which the linked sage advice affects.
