D&D 5E Greater Invis and Stealth checks, how do you rule it?

[Crimson Longinus]

They did. Its in the opening chapter of the combat section.

No. The rules do not define 'notice' as 'be aware of exact location'. If Crawford wanted it to be there then he should have written it, but he didn't.

 

[NotAYakk]

How? That is blatantly absurd. If an invisible person stands silently in a middle of the field, 60 feet from you, how the naughty word would you know they're there? Perhaps some amazing super scout could possibly perceive the sound of their breathing, or some blades of leaf their feet had crushed or smell their sweat, but all of these seem like crazy difficult tasks to me, and of course an auto success would be blatantly laughable idea in such circumstances.

Again, how? If no one perceived them to go there, they were there from the beginning of the encounter, then auto-detecting them would be utterly bizarre. You're basically giving all creatures some absurd radar. Does this work through dungeon walls too? Can I detect secret passages by drawing my sword and being automatically aware of every rat or bug that could be behind the stone wall?

Um, someone sitting in the middle of a field invisible and not moving is describing someone who took the hide action.

If a monster, that is just assumed. If a PC, the player describes what the PC is doing, and the DM says "that is the hide action" and tells the player to roll stealth.

(The player describes what the character is doing, the DM provides the mechanics)

The case where you are invisible and not hidden basically requires you to be frantically doing something besides trying to be not spotted every 5 seconds from the moment you where invisible and the enemy knew where you are, to the current time (moving, attacking, sprinting at top speed, casting a spell, messing with your gear, drinking a potion, whatever).

You don't know the exact location of the invisble (but not hidden) monk.

You have a rough idea. Enough to make some attacks against it with disadvantage. Not enough to target it with 90 percent of spells and other abilities (barring area attacks) or to make opportunity attacks against it.

This this a million times this.

Ok invisible monk its your turn, what do you do?

I stand still and keep quiet while being unseen thanks to my invsibility.

Ok, that's the Hide action, make me a Stealth check.

 

[Helldritch]

I am using logic, and the rules.

Not from my point of view, sorry. You are just blindly and recklessly applying a rule.

And he can see (footprints) and hear (footsteps, heavy breathing) the Monk.

He won't see foot prints, the place is made of stone, a castle you know... He won't hear heavy breathing, he is running too in heavy armor, that alone makes a lot of noise.

Close your eyes. Ill run past you in fresking sneakers. I assure you you'll be able to discern the direction im coming from and the direction im heading with sufficient accuracy for several seconds to be able to put a bullet in me with a handgun.

Will you be as accurate as you would with an aimed shot? Nope. But you'll have a mental image of where I'm at

Yeah... so you say. I'm not a monk. But I'm not a sneaky type either. I can assure you that if I am screaming for the guards and try to get to you blind folded, I will lose track of you almost immediately.

Can i run away from you for several seconds, then stop and start tiptoeing away on a different angle causing you to lose track of where im at?

Yep. But that's just me taking the Hide action on my second turn.

This I can agree. But I would not even hear you running if I were screaming for the guards either.

What do you change the default to, then? I'm curious. Because, you know, default just means the usual, so what do you change the usual to?

I personally don't have a "default", I just make a call based on the situation.

In general, it depends on how noisy the invisible creature is relative to the environment and how much it interacts with the environment. But it all comes back to making a judgement call, what could be perceived? I take into allowance the fact that some PCs are far more perceptive than I am, but there are still limits.

• Flying creatures in an open area are difficult to detect, particularly smaller creatures (no detectable down-draft). An invisible imp flying above the market is going to be nearly impossible to detect unless they disturb some birds, fly through smoke or similar. Of course it will change if the imp is screaming epithets or throwing things.
• In situations that are relatively quiet, I'll probably require a stealth check. Sneaking past the guard (before combat) is an example. I may adjust and give advantage/disadvantage based on environmental factors.
• In combat it depends. Mass battle chaos or 4 PCs vs 1 opponent in a quiet cave?
• Environment matters. On a city street? Middle of the day with people running and screaming because a balrog just gated in or middle of the night? Storm and wind meaning you have to yell to be heard or calm and quiet?
• Is the ground wet, covered in snow or is there another reason to leave tracks such as walking under cover during a rainstorm?

But for me, I don't have a huge issue in part because I don't have 5 minute work days and I've never given out items that grant greater invisibility equivalent. Spell slots (even at higher levels) are pretty precious and greater invisibility only lasts a minute. If the PCs can take advantage of this now and then, fantastic. It's more of an issue with creatures that have greater invisibility, but that just gives me options to throw different challenges. The scouting invisible imp or sprite familiar is probably the biggest headache I ever have. Then again, lanterns of revealing aren't that expensive to have scattered around in highly secure areas. YMMV.

I don't see the OP's scenario being all that much different from what happened in a recent game. The PCs were placed in magical darkness by monsters that could see in the dark (orc blades of something or other I think). I rolled straight dex checks for the orcs vs passive perception; there was a decent chance the PCs would know where the orcs were but not guaranteed. This was in the abandoned part of the city, outdoors so not dead silent and a mix of hard and soft ground. Depending on if the PCs beat the dex check and by how much they either had a pretty good idea of location or just a general direction.

So moving far away could make you unheard. How did you get there unheard? Are you making attacks from that position or just chilling, trying not to be noticed? Sounds a bit like Hide either way. Sure, DM call can cover that - but, and you clipped this part of my prior post, are you giving them a free Hide (with the mechanical benefits that come with it) and allowing other actions?

Yes, circumstances such as your questions above can modify things. We are talking in general here.

Also, becoming hidden due to unseen due to invisibility, and unheard due to circumstances, is not a free hide. It costs a 2nd level slot and concentration. It's the rules, not me, that state that hidden = unseen and unheard.

I'm not sure I follow your example. What is the invisible PC in the noisy tavern trying to accomplish and how are they going about doing it? Since they are not trying to be quiet, it doesn't seem to involve Stealth.

i don't know. In a game I would know what they are trying to accomplish and how, and would adjust accordingly.

As for not involving stealth, you don't always have to be stealthy to be unheard. I don't know if your ever been go a big play or musical, but it gets so loud just by talking that you have to lean into the person next to you or shout, just to be heard. Fewer people, such as at a noisy tavern would similarly, though to a lesser degree, mask noises. That's what the DC is for. Combat is louder than a tavern.[/Quote]

This is exactly how I run things too.

 

[Hriston]

I don't use passive rules. However, a moderate DC is 15, so most passive perceptions wont pick that up.

So the optimal strategy for my DEX 8 fighter in full plate who wants to remain unnoticed is to get behind a boulder and NOT try to hide. Got it!

Sure, but when I set that DC to notice, IF I set a DC at all and don't just rule auto failure, the DC will not be a moderate 15.
