Remember that the rules explicitly tell you to use Athletics to make a longer than normal jump (even if they don't tell you exactly what the DCs and results are, as they did in 3.x). So no -- a 20th level fighter is not limited in the way you describe -- you just have to roll. And that roll represents the same uncertainty that an Olympic athlete deals with every time they get up there. There are 3 medals for a reason.Yup, a lv 20 Fighter should match or exceed any world records. For example, the world record for a standing long jump is a little short of 12 feet 3 inches. In D&D, to break that World Record would require a strength score of 26!!! Even a Barbarian with their maximum 24 STR at level 20 falls short of that.
That's not true. it is a game after all.The mechanical perspective is irrelevant as long as it achieves the desired narrative ends.
Now we are getting somewhere. Those sound like good feats or maneuvers or "archer archetype" features. What's the problem?Here's a few ways that splitting the arrow could be accomplished in mechanical terms:
1) The fighter can make a called shot, automatically striking the intended point if an object, or automatically getting a critical hit if a creature. You can use this X times.
2) When you hit, your next attack is automatically upgraded. An upgraded attack becomes a hit if you rolled a miss, a critical hit if you rolled a hit, or deals one extra weapon die of damage if you rolled a critical hit. An upgraded attack does not upgrade the next attack.
3) If you attack an inanimate object, it it an automatic critical hit.
There's three completely different mechanical implementations of the same narrative conceit.
I am not sure why you think the fighter shooting the rope is GM fiat. The rope has an AC and HP.As to when you would use it? How about when an NPC is about to be hanged and you want to show off by slicing through the rope with an arrow? I realize that's pushing the bounds of realism, but it's hella cool and definitely something a player might want to attempt. The fighter player is at the mercy of the DM. Meanwhile, the wizard player can cast Shatter on the rope and probably auto succeed (despite the silliness of shattering a rope).
