While I didn’t know the RAW ruling on a Readied Attack action preventing the Extra Attack last campaign, preventing the use of the feature for a Readied Action doesn’t seem particularly FUN. I may just House-rule that the feature functions in that case. Fun > Raw, in my games. “fun > RAW” *is* RAW

This does open the door to characters not attacking on their turn, knocking opponents prone during the monster turn and attacking them at adv. Then, the monster will likely not have enough movement to stand back up, forcing all of their attacks at dis. Not bad, just a thing True, but if you have a group that is going to exploit such a house rule in this way, THEN perhaps you best not use this house rule! 😉
I don’t see my group being this way, so it should be fine.

Do you let monsters with Multiattack that Ready Actions use the full Multiattack? If I allow it for my players, then why wouldn’t I allow it for their enemies? 😉

The only issue with this, I had players come to me demanding to house rule at their convenience, it is also the DMs discretion and opinions about rules, I like the RAW version of it. I agree, one should not immediately bend to player whims, but this was only spurred by my thinking on the ruling and genuinely not finding it as fun from a DM perspective.

I’ve just scoured my books to find out where it says that this is the case, and the only thing I can find is that a readied spell must have a casting time of one action. I didn’t realize though that readied actions count as your reaction for that round. It’s that the Extra Attack feature as written only triggers if you take the Attack action on your turn. Since the Readied action allows the Attack action out-of-turn, it gets a bit sticky.

I think I still assume holding and readying work the way they did in 3E and so far none of my players have complained or noticed it doesn't work that way (if it doesn't!)
