Mod Note:
How about you try to be about 70% less insulting going forward, please and thanks.
Apologies if you took it as an insult. For clarity, the 'you with a Strength score less than (body weight/30)' I was referring to is the 'you' in game (a PC, NPC or Creature who has an actual Strength score), not the actual poster I was quoting (I have no idea if Oofta can climb a rope or not, and in any event, he doesn't have a Strength score represented on 3d6).
But allow me to rephrase for clarity:
''If
a game world human can't do it, it's because
the game world human has custard arms or they're obese (their Strength score is less than (weight in lbs/30).''
In game, a 290lbs Human PC or NPC can lift his own weight off the ground with a Strength score of 10 (Commoner) which would put that commoner in the 'morbidly obese' category.
I suppose a non-obese PC or NPC might have some kind of a weird grip stopping them from being able to yank a rope with (bodyweight) weight off the ground, or be missing thumbs, or have a weak rotator cuff or shoulder joints, or something odd.
But 'average healthy real-world humans' can climb ropes, reliably, every single time:
To flip it back into game terms again, these guys aren't falling off the ropes, or unable to climb the ropes 50 percent of the time (DC 10) or even 5 percent of the time (DC 5). The tiny minority -of these real-world people- that cant climb ropes would - again - flipping back in game terms - have low Strength scores (less than total weight of them and gear/30).
To keep it in game terms, they've joined the Army with Strength scores of 5-6 or so, and weigh over 150-180lbs.
Hope that clears that up.
