I use it as it is commonly used. You'll need to prove your bold claim there. Since I don't believe that you can't prove it, I'll ask why you have the opinion that +5 must be the baseline, and +4 must not be?
So you mean as in goodly, saintly, kindly ect? No, I don't believe that the stats have anything to do with a good character. So, what do you mean by "how it is commonly used" because the word "good" is commonly used in about a dozen contexts, especially in gaming circles, especially when you get to different paradigms. Like I said, I'm using thinking in terms of meeting the expected baseline.
Since you don't believe I can't prove it (likely because I have done so multiple times) I'll make this quick, especially since it is 1 AM and I am too tired.
First reason I expect it is the baseline: Because of the basic math of the game. The standard array of stats has the highest stat as a 15. Baseline human is +1 in all stats, so their highest stat will be a 16. Proficiency bonus is a +2, meaning that the simplest and easiest character to make (A Human X with their prime stat as their highest) will have a 16 in their main stat.
Second reason is the fairly well accepted math that has shown that a +5 at levels 1 thru 3 gives a 65% success rate against average ACs, DCs, ect, which then trails off and is bumped at various levels as we expect to get stat increases and proficiency increases. I've seen this mentioned in multiple places.
Going back to the first reason, why would I expect that a character with a class would put their highest stat in their prime stat? Because the game tells you to. In the quick builds for every class it lists a primary stat which should be your highest.
So, yes, a 16 in your prime stat is the expected baseline. You would have to either not put your highest stat in your prime, or actively choose a race that does not increase your prime stat to avoid it. Something the game subtly points to as not encouraged, not only from the quick builds, but also in the table that lists all of the ASIs for the various races, making them easy to reference, right in the same place that they demonstrate matching race and class to get your prime stats to 16 or 17.
The bold explains it. It's just their personal feeling.
So your explanation for why they felt someway is because they felt someway... In your mind are feelings utterly arbitrary and indicative of nothing? Because I don't understand how saying that their feelings are their feelings in anyway answers the question of why.
You expect me to believe that? Nothing ever failed it's save against your spells at +4, but would have failed enough to make it worthwhile at +5? That +1 difference meant the difference between nothing failing to save and the spell is suddenly worthwhile?
No, I expect you to fight me tooth and nail and decry everything I say as a lie, a twisting of the truth or ignorance. But I hope you might actually listen to what I am saying.
Would a +1 have made all the difference? Well, the game was 5 years ago and I didn't really make a log of every single roll ever made, so I can't say that with scientific accuracy. However, those two characters who had less than 16 in their primary attributes are the only two clerics and really the only two spellcasters I have seen in 9 years of this game to have this problem. Even other casters who missed quite often never felt so frustrating. To either me, or the other player.
That +1 to hit and +1 to DCs and +1 spells prepared or known does make a difference. You can scoff at me all you want about how that can't possibly be true, and yet, two different characters with the exact same issue, years and tables apart, under two different DMs points to there being something to it.
All because he started with a 14 instead of a 16? I'm not going to believe that even if a player somehow felt that he was weaker do the lack of +1, magic items providing +1 wouldn't fix it.
There weren't +1 items for cleric spell DCs at the time. I did end up with him having about 5 magic items to everyone elses two or three, and he still felt weaker than all of those other characters.
It sounds very much like a psychological issue to me. I'm not saying or implying that you guys are insane, so don't go into left field on me again. I'm just saying that if a PC is lacking +1 and you provide that +1 via magic items, the issue is objectively gone. If the player still feels like he's weaker, that perception is just in his head and not actually true. The same with the misperception that the lack of +1 causes everything make it's save against your spells, but having that +1 means that the spell is now useful.
You are assuming the items were giving him a +1 to spells, they weren't.
And, maybe it is psychological more than mathematical, but two different people, years apart, at different tables with different DMs reporting the same psychological effect? Seems a stretch, unless there is something too it. And, considering that psychological effects are still real, at least real enough to move multi-million dollar enterprises, I wouldn't just dismiss them as something people should "get over" either.
I've never said or implied that the baseline bonus for a PC's main stat is 0. This is not a reasonable assumption to make from what I have been arguing here.
Third times the charm.
Then what did you mean by saying "
The baseline assumption should be 0." If you would explain yourself, this whole process could go a lot faster than me repeatedly asking you to answer the same question over and over again.
I've been talking about the racial averages and racial stat bonuses. I've not once talked about or implied that PCs are average or that the baseline should be 0. That's a complete fabrication on your part.
Those are literally your words, from this post right here.
The baseline assumption should be 0. If you want to optimize for every little extra +, then pick a race that gives you that bonus. There are lots of races that give dex and multiple races that give charisma, and a bunch that give both. It's not hard to find one that will give you what you want.
Please Max, stop accusing me of fabricating things I can literally quote you saying. It is insulting.
You've made the claim yes. Demonstrated it? No. Raising the racial dex average of a race that is more dexterous by giving it +2 does change the flavor and add more realism.
No, it doesn't change the flavor of them at all. No, it is not more realistic to lock them in to these bonuses.
Sure it does. The rules that limit PCs don't limit NPCs. This is why NPC wizards and such have abilities that PC wizards don't and vice versa. They've learned different things.
And can PCs learn the abilities of NPCs? No. Therefore just because it is a leanred ability doesn't mean everyone is capable of learning those abilities. Therefore, my previous answer stands. Some people are incapable of learning things that others can learn to do.
Now you're implying that Cirque du Solei gymnasts are born to Cirque du Solei gymnasts and nobody else can learn it. The fact is, anyone from any part of the world who is born with a slender body type can learn how to do it. So while elves might all be slender and able to learn X ability, any human, orc, hobgoblin or triton with the same body type could also learn it.
"With a slender body type" ie someone without a slender body type, who is born broader of shoulder or with a metabolism that leaves them husky can't learn it.
So, exactly what I said. Yes, people can learn to be gymnasts and acrobats, but some people are simply not capable of the amount of flexibility they are required to learn.
Someone with the ability helps you learn how to use your mind to project your thoughts. With practice and hard work, you eventually become able to do so and gain that feat.
Sorry, but the feat doesn't require I get a teacher. And who says it can be learned at all. A lot of psychic stories involve it being something you are born with and must learn to use. A learned skill that is rooted in how you are born. Again.
And do you really think that only Tabaxi have claws? Any intelligent race with claws should be able to learn to retract them. Just like any race with scales should be able to take the ability to have tougher scales.
Actually I was referring the Dragon Hide feat, that says that the dragonborn who take it gain sharp retractable claws and tougher scales. Tell me, how did they learn to grow tougher scales than they were born with? What book did they study to pull that off? What did they learn to change their non-retractable claws into retractable ones, because that is a biological feature, you literally have to be born with that ability, that's why cats are one of the few species capable of retracting their claws, and most species aren't. It requires special muscles and a space to retract the claws into.
And we see from the game that anyone who wants to can learn to be lucky. They weren't lucky from levels 1-3 and now at level 4 they are!
Right, so how do you learn to be lucky? You are 100% confident that it is a learned skill, how do you learn it?
There's a reason why this is at the beginning of the DMG,
"The D&D rules help you and the other players have a good time, but the rules aren't in charge. You're the DM, and you are in charge of the game."
The designers understand that the rules when applied as written to every situation will break down in some of them, like your tiny spider example. They expect that the DM will recognize absurd situations like that and just say no. The DM should make a ruling over the rule, like the game's mantra says.
Great, so even if the rules say Elves don't get a +2 to dex, and you say that means the rules are saying elves aren't graceful, you can recongize that is absurd and say that actually elves are graceful even without the +2 Dex.
Rulings not rules Max, just like the game's mantra.
