Again, I’m not saying an 80 foot height isn’t sufficiently similar to the example complications in the rules. I’m saying it isn’t a complication. It’s not even an apples to oranges comparison, it’s an apples to Fallout Boy comparison. The height of a climb isn’t a factor that makes the climb more complicated. Stress might be a factor that makes a climb more complicated, but it isn’t the DM’s purview to decide for a player that their character is stressed.
I’m not sure I agree. If the DM determined that, like, the rough texture of the rope on the character’s hands was a complicating factor warranting a check, that would be a silly but by-the-rules ruling. But determining that the day of the week is a complicating factor? I don’t think that’s within the purview of what the rules describe, because it isn’t something that could affect the complexity of the climb.
I see what you’re saying, but words also mean things. Some things simply aren’t complications. If you decide the price of tea in Kara-Tur is a complicating factor in a player’s ability to climb a rope... I don’t think that’s in keeping with the rules.
