Those examples show the paradox. If you don't take the Attack action, you are not satisfying the requirement in Shield Master which allows the bonus action to begin with. In order to gain the bonus action, you must take the Attack action on your turn. I am showing you exactly how you can be denied your Attack action, thus you have no granted Bonus action. But, oh, wait, you already used it! How can that be since you didn't meet the requirements for it??? THAT is the paradox you seem oblivious to...
But that "paradox" is of your own creation and is easily solved! Don't allocate a bonus action to the shove-attempt until the condition for it has been met. See how easy that is?
This is getting laughable. You are basically arguing this: you shove, and if that shove is followed by the Attack action, then you must have used a bonus action to do it because you are using the Attack action now. But, if for some reason, you are denied your Attack action after the shove, then you are just saying your Attack action is what was used for the shove. I'm sorry, but that is pretty bad logic there. You have to decide the source of the ability that allows you to take an action before you use it, not afterwards.
Why?
You cannot exchange bonus actions for actions and vice versa.
I'm not doing that.
The paradox is that you used a bonus action granted by a feat and then did not satisfy the condition required to earn that bonus action. "The incongruity seems to arise from assigning a bonus action to the shove-attempt before the condition has been met for using one." Exactly, THAT is precisely what you ARE doing!
No, it isn't. That's precisely what I'm recommending you not do to avoid creating the paradox you keep creating.
If you want to shove, how are you doing it? Are you using your Attack action to shove? Ok, go ahead. Are you using the bonus action from Shield Master? Sure, but only if you take the Attack action. No problem I suppose--UNLESS you are denied the ability to take the Attack action. Again, paradox.
Suppose you have 1 hit point left and you are facing an orc and a goblin. The orc is going first and the DM decides to Ready the orc's action to Attack if you shove the goblin and knock him prone. You turn comes and you knock the goblin prone using your bonus shove from Shield Master. Since the triggering event occured, the DM has the orc use its reaction to attack you and it hits, knocking you to 0 hit points. You are now unconscious. You used the bonus action from Shield Master, but never used the Attack action that would grant it. Again, paradox. You can't switch what action caused you to shove after the fact.
This is a very odd view of the rules which keeps coming up in this conversation. It's the idea that my character needs explicit permission from the rule-books to do something entirely mundane that anyone in the real world can do. In the real world, if I want to shove someone, I don't need to "use an action" to do so. I can just extend my arm, or whatever, and apply the physical force that I wish to. That's all that's required of my action-declaration in the game as well. All I need to express at the table is that my character shoves a creature within 5 feet, and that my character's goal is to push the creature back or to knock it prone. It isn't an action or a bonus action that causes my character to shove a creature. It's my action-declaration that causes it.
Except for the fact that he reversed his original ruling on how Shield Master works, so you can doubt it all you want but the evidence of his reversal suggests otherwise.
No, it doesn't. He also reversed his ruling on War Magic. I think the reason for his reversal should be taken at face-value: he decided that the conditions for both the War Magic and Shield Master bonus actions (among others) do indeed constitute a timing specification. I'll repeat that he has gone on record that the decisions made in development about bonus action timing weren't made for balance reasons, but rather to keep the game moving.
Except you have. You gained the shove. What benefit is that to you without your Attack action to follow it? Maybe not much, except if you have allies nearby who can still benefit from it. What benefit the bonus action Shove is without your own personal Attack action is situational.
But I could have shoved a creature anyway. Therefore, gaining the ability to shove a creature is of no additional benefit.
Good, we are making progress at least. We agree you can always shove if you have another means of making an attack, such as through the Attack action.
I don't see how this is progress. I've never held or expressed any other opinion. Have we overcome some assumption you were making about me?
You keep bringing War Magic into this. Maybe that was my fault and I did a while back, I honestly don't remember, but can we agree to keep War Magic out of it? It is a needless complication which cannot prove your point, however much you like to think possible RAI can.
No, I won't agree to that. Here's the full tweet of the ruling dated July 6, 2015:
Does the “when” in the Eldritch Knight’s War Magic feature mean the bonus attack comes after you cast the cantrip, or can it come before? The intent is that the bonus attack can come before or after the cantrip.
This unequivocally establishes RAI for bonus action timing of "conditioned" bonus actions like the shield master shove, i.e. there is no specified timing. You may remember that the RAI of Shield Master was a contentious issue up-thread in my conversation with [MENTION=6921966]Asgorath[/MENTION], and I'm somewhat surprised they haven't conceded the point in light of this overwhelming evidence.
There is no lack of timing. It is very explicit in the SA for Shield Master.
I said, "
intended lack of a timing specification." The timing specification that Jeremy Crawford has added to the game since he revised the War Magic ruling in the 2017 Sage Advice Compendium is the unintended result of a hyper-literalistic reading of rules-text which failed to reliably convey its intended meaning to enough people. It's a terrible reason for a ruling, IMO. What they should have done instead is issue errata to make the text in question conform more closely to its intended meaning.
The point above indicates you don't understand the official ruling on the timing element of Shield Master, which of course is the entire basis for the point that the shove comes after you've taken the Attack action.
I'm sorry, but I'm not following what point you think indicates this. I'm pretty confident that I understand Crawford's reasoning, though. I just don't agree that his is the only valid interpretation.
You can disagree with it all you want. Heck, I don't agree with it, and if that is all this boils down to then what are we wasting all this time for? Just say you house-rule it and be done with it. Is there some reason you don't want to say that? Do you think house-rules are a bad thing?
We've house-ruled it. I can freely say that. Our table doesn't like the official ruling so we allow the attack-shove-extra attack variant that we like. It sort of follows the official rule... you did take the Attack action first, but we just don't follow part 2 that the Attack action must be completed in its entirety. Works for us.
I find it odd how much you conflate the official ruling with the rules (RAW). They aren't the same thing, and not following Crawford's ruling doesn't require a house-rule, which I have nothing against, but in this case it isn't necessary.
Now, it is late. I've had a long day at work and the next few days will also be long days. If you reply and I don't have time to respond before the weekend, please be patient and accept my apologies.
No worries!
