Out of Character

I'll have to write down all this disadvantage stuff, because since I can go a few days before the dragon attacks again, it is hard to remember who is dodging and who has some special ability up.

Ok, so the tail attack that had hit Isaiah actually missed. I rerolled the 2nd claw attack that still went for Isaiah and it still hit (new roll was a 23) so the 12 damage from that still happened.

yeah...doesn't help I took the dodge action. Who takes the dodge action.

Putting in spoilers in case people don't want to go above the table if DM doesn't want just delete my post

@Ironmonger42 do you have any issues with following use of Wall of Stone spell: I would make a 10x10x10 foot cube box covered from 3 sides and top + last two sides would prevent dragon reaching inside while allow PC to to move in/out (for a ranged attach at the creature who is so high (40 feet) that I will always have line of sight) without a problem

I don't think that breaks any rules of the spell. I read it again, and as long as each wall touches at least one other wall it should be fine. Keep in mind the panels have AC 15 and 30 HP, so a multiattack or breath weapon will probably bring a pannel or the whole thing down.

I'm not sure what would happen if it used its breath weapon to destroy a pannel and you were still in the path after the pannel was blown away. Would you be safe because when the breath weapon started you were in full cover, or would you be affected because with the panel being closer and then destroyed by the time it got to you the panel would be gone?

1) Wall of stone say
The wall is 6 inches thick and is composed of ten 10-foot-by-10-foot panels.
Each panel has AC 15 and 30 hit points per inch of thickness.
My math say it's 180 HP for Each 10x10 panel

2) Doesn't breath weapon and wing attack say "Each creature in that area ..." wall is not a creature. Up to DM, but if dragon "Wing Attack" could finish off stone wall, 3 little pigs is a lie LOL

For the first point, I missed the "per inch of thickness" part.

As for the second part, there's a lot of grey area there. Red dragon uses the same language, but if a red dragon breathed on a tree, you'd assume it would take damage, but a tree (that's not a treant) is not a creature. On the other hand, spells like eldritch blast also says "A beam of crackling energy streaks toward a creature within range", thus by that ruling eldritch blast cannot harm objects but most people I hear about say it can damage objects because it should be able to.

Final ruling: It depends on the feature/action/spell/etc., but if it makes sense that objects would be damaged then they will be as if they failed their saving throw. If an attack roll is involved, the DM will assign an AC based on the DMG's suggested ACs based on materials. As such, lightning breath and wing attack can damage objects, because lightning breath involves raw electrical energy being forced into the object which would harm it unless it is an object immune to electricity (like rubber) and wing attack will always damage an object as a wing slamming into an object is no different than a monk punching the object.

Your ruling is noted, but I stay with my turn anyway.

P.S. If we take 5e designers seriously, they have explained here why they insist eldritch blast can't damage objects

The designers have a point with eldritch blast, but there are plenty of examples of spells that only target creatures, but we have to use logic like "magic doesn't work any way other than what it states" when you have situations like chromatic orb also saying "creature" instead of "creature or object", so not arguing eldritch blast should work on objects but saying there are plenty of cases where either the designers forgot a word/phase or don't make the most sense.

Disclaimer: I'm totally fine with ruling magical structure created and supported by spell caster concentration (wall of stone spell) is subject to damage as per DM discretion.

Now I only want to share some piece of advice for those who believe 5e is a low quality and neglectful wording of their their features/spells need to be fixed more often than not. Feel free to ignore and not read my advice or ignore if you don't find it valuable. It is just and advice.

Also, I totally forgot I had the luckstone. So my ability checks and Saving Throws should be +1 on top of what I roll...not going to try and figure out if I failed one of those WIS throws by 1. so Just going to make use of it now on

All good... Hard thing about one shots if remembering stuff about a character you didn't play for very long

I can't make a wisdom save to save my life. I am useless until then (and probably useless at that point as well if he is in the air, literally can't hit him with anything)

At this level, I think the designers figured players would have some way to ground the dragon somewhat reliably, be it someone casting fly on the barbarian who would then go up and grapple it down, or spamming earth bind until it works, or similar things

totally, though I don't think we are the most "well rounded" party in that regard. Maybe Isiah has something but Omeros probably doesn't have something as a Warlock, and the rest are melee combatants for the most part it seems.

I am basically relying on my PAM Opportunity attacks at this point and being a distraction maybe. Maybe Command? but I am already running low on those spell slots

Keep in mind that the dragon is bloodied, so with my experimental version of the legendary resistance trait, the dragon is now susceptible to saving throws and and can fail ability checks to escape effects, even though it hasn't used any charges yet.
