As a matter of stylistic preference, I kind of make it a point that real people can't. That you need to be heroic to survive.
That said, I do think it's (darkly) amusing that many fans of games, shows, and movies don't realize how incredibly deadly humans are. The Monster Manual is full of creatures that frankly wouldn't pose much of a threat even to Stone Age humans, let alone modern technology. Recent research indicates our ancestors wreaked devastation on all megafauna tens of thousands of years before we invented gunpower or even metalworking. They reliably took down elephants and mammoths with stone-tipped javelins, and only got more dangerous from there. The reality is that D&D actually nerfs humans, particularly human weaponry, far more than most realize.
So while I tend to rely on supernatural elements to create existential threats, I think OP's question changes depending on the context. There is a significant difference between reality vs. "real humans" as D&D characters without special abilities, and it's the latter that's far weaker.
Here:I don't understand why you keep say "as per the OP" for things that I can't find in the OP.
You'd have to ask @Zubatcarteira concerning that. The bolded part above would indicate those rules wouldn't be applicable IMO, so I go with that.Being a "real human" doesn't mean you can't have levels. In fact, 3e had rules for high level mundane NPCs that explicitly had no special abilities, but still had things like HP, skills, and other basic class mechanics. So you could easily have a level 20 Commoner or Aristocrat.
Yeah, it was sort of stupid if it acted like that. But hey, white dragons were the lowest intelligence dragon, so sure...That's how you fight superior foe. Ambush tactics. Not so remote, it was part of dwarven kingdom, one of their supply routes. Dragon wasn't stupid. It knew dwarfs use those mountain roads to haul goods, which was primo place for easy fly by plundering of livestock and food supply. So party tracked dragon movements, patterns, with help from caravan people and route wardens. Extensive scouting and research about foe was done, so was in choosing right time and spot for setting ambush point.
Yeah, I know how AD&D played, 1E as well as 2E. Played it for decades.Lv 4 in 2ed AD&D. Our party fighter had 15HP, ranger 18, thief had 10, wizard was at 8. Don't know if you played it, but you rolled for HP at every level, even first. So fighter with 1 hp at lv1 was also possible. Also, stats were 3d6, arrange as you wish, so good luck getting that extra 15 needed to put into CON for extra 1 hp per level. Normal human would definitely fall into lv 3-4 ad&d character. As in, 1-2 good hits from sword and you are dead.
FWIW, I know about pill boxes, military strategy, etc. I don't need the details on that, myself.No. It was just few sessions of extensive prep work to set things in place, formulate plan, gather equipment, resources etc. Overlapping fields of fire, negating one big dragons advantage (flight), surprise attack with artillery, and of course, right spot. Pillboxes where just basic round low stone buildings with slits for crossbows, same type farmers build across our islands for hundreds of years ( they are built across Mediterranean region,specially islands) as shelter from storms. Built couple with my grandpa as a kid in our olive gardens. Fighting dragon in narrow gorge is like infantry fighting tanks in urban environment, same tactical principles, modified for fantasy.
More realistic, yes, but not realistic when it comes to "normal humans". Commoners in 5E, by comparison, have a chance of survival not much worse than some 1st-level characters in 5E, if they "play it very smart and don't try to act a hero."As i said, 2ed was much more realistic, specially low levels. Low hp, low to hit, you needed way higher stats for bonuses (at least 15, sometimes even 16). So normal humans have same chance as PCs to survive low level adventures. They just have to play it very smart and don't try to act a hero.
While you have a valid point, I think it is important to also look at the other side... humans did take down elephants, mammoths, etc. but often times were injured or died in the process. It was also typically several humans vs. one creature, which they ran to exhaustion, harassing, etc. the entire time.The Monster Manual is full of creatures that frankly wouldn't pose much of a threat even to Stone Age humans, let alone modern technology. Recent research indicates our ancestors wreaked devastation on all megafauna tens of thousands of years before we invented gunpower or even metalworking. They reliably took down elephants and mammoths with stone-tipped javelins, and only got more dangerous from there. The reality is that D&D actually nerfs humans, particularly human weaponry, far more than most realize.
You'd be lucky to last one encounter if the bear actually wanted to harm you. We have a lot of bears where I live. Fortunately, they want nothing to do with people.So at level 1, a "medium" encounter might pit me and 3 friends against a brown bear, a creature that weighs between 180 and 1300 lbs, that can run 35mph.
And under 5e expectations, me and my 3 friends might take this match 6-8 times in a day.
Would we survive? Absolutely not. Each bear has a punchers' chance to eviscerate a member of the party every encounter, and each party member eviscerated makes the subsequent combat more dangerous.
We'd be lucky to last a week.
Add weapons base max damage to attack roll.I don't care what it is, should be able to deal only 1 point of damage, regardless of modifiers.
Screw bears, I've hiked around enough of them to know that one way to stay safe is have an Akita inside your tent.You'd be lucky to last one encounter if the bear actually wanted to harm you. We have a lot of bears where I live. Fortunately, they want nothing to do with people.
