There is also no rule stating that’s humans don’t get resistance to fire. Guess that’s entirely up to the DM as well…
I don’t like how your principles lead to absurd interpretations.
LOL, please STOP, just STOP! You are making me LAUGH SO HARD!!!


Seriously, this response is just ridiculous. There IS a rule explicitly stating what racial traits are, and who gets what. Please don't waste my time further.
I did manage to track down which particular line likely led me to thinking that way. "On your turn, you can move a distance up to your speed and take one action. You decide whether to move first or take your action first" seems to indicate to me that it's intended that you complete your action before doing other things. But again, this is mostly pedantic argument because it is a gray area.
I can see how you might think this, but again this is about movement and actions, not about actions and (bonus) actions. It might indicatate that to you, but that isn't what it actually says concerning actions and actions. The section on Breaking Up Your Move says you can move, take your action, and move again. You don't have to move and then act, or act and then move (you
can of course!), which is more what your quote (bolded) would indicate.
I also think its simply more likely that the designers simply never considered the rules application of taking another action mid action because 99% of the time it will never come up. You never have to worry about "can someone take another action mid fireball?" because fireball isn't broken up into discrete parts. Other then Multi-attack and a few odd spells like chain lightning most actions don't have multiple steps to resolve them where in someone could do something else.
True. I agree it is an issue which the designers overlooked. It has come up numerous times, such as Shield Master, which the designers have flip-flopped on. First is was you have to complete the Attack action before you can bonus action shove. Then it became you have to take the Attack action, allowing you to bonus action shove after just one attack, and finish attacking after the shove.
All of this simply returns me to my initial position: there is no rule in either direction, so it really is just up to the DM...
P.S. as a related question (and this isn't meant as some kind of gotcha Im just genuinely interested in what your ruling would be based on your previous posts) what would you say if someone wanted to action surge mid chain lightning? After the initial hit but before the secondary bolts.
No worries. I feel your posts are in good faith and I wouldn't see this as a "gotcha" anyway.
My ruling would be "no" simply because the spell (like
eldritch blast above) is instantaneous. I wouldn't allow someone to move between the separate rays of
eldritch blast, either. The section on Moving Between Attacks is about "weapon" attacks, not spell attacks.
Now, its interesting, JC has stated the rays in EB were meant to be completed consecutively. So, if you hit a target and kill it, the next blast isn't wasted and can target a different foe.
Chain Lightning allows you to pick up to to three targets after the first, and all targets are hit instantly. There is literally no time to Action Surge for another action before the spell is resolved.
The Attack action isn't instantaneous IMO. Sure, nothing says it "isn't", and nothing says it "is", so DMs and Players get to run things in whatever way makes the most sense to them.
I probably would, whether the extra Action came form Action Surge or haste. I'd also allow the caster to move between bolts (if they have the movement for it.)
And here is a perfect response in the other direction from mine. Totally valid and if I played with such a DM it wouldn't bother me at all.
As you know from my (I believe) first post, not every situation or scenario is covered in the rules. Logical use of the time permitted in the game, use of features, spells, etc. break up that time in a way which just has to make sense (and FUN!) to those who play. That's all.
