And what's with these ginormous jumps, too. I still feel like it's ridiculous and like super heroes jumping around all over the place. There's a jump that is obviously like 15 feet wide, but my character can jump 30 feet, so we're good.
Your Strength determines how far you can jump. Long Jump. When you make a long jump, you cover a number of feet up to your Strength score if you move at least 10 feet on foot immediately before the jump. When you make a standing long jump, you can leap only half that distance. Either way, each foot you clear on the jump costs a foot of movement.
THIS is how it should be done. So, if I'm in combat, and I jump away from an enemy, if my Strength score is 15, I should only be able to jump maybe 7 or 8 feet. If I'm not in combat, and I jump over a gap, that gap should be no more than 15 feet. I should see my character run and jump automatically over the gap. If it is more than 15 feet, my character should stop and say, "Sorry. I can't make that. It's too far a jump." Or something like that.
This rule assumes that the height of your jump doesn’t matter, such as a jump across a stream or chasm. At your GM’s option, you must succeed on a DC 10 Strength (Athletics) check to clear a low obstacle (no taller than a quarter of the jump’s distance), such as a hedge or low wall. Otherwise, you hit it. When you land in Difficult Terrain, you must succeed on a DC 10 Dexterity (Acrobatics) check to land on your feet. Otherwise, you land prone.
High Jump. When you make a high jump, you leap into the air a number of feet equal to 3 + your Strength modifier if you move at least 10 feet on foot immediately before the jump. So, out of combat, you should be able to jump up, with Strength 15, 5 feet. That's it. 5 feet! Not this crazy stuff Larian's got going on where Lae'zel can jump up into the air like 20 feet.
When you make a standing high jump, (so when in combat), you can jump only half that distance. So what is that? 2 feet? Maybe 3? Either way, each foot you clear on the jump costs a foot of movement. It's not an action or a Bonus Action. In some circumstances, your GM might allow you to make a Strength (Athletics) check to jump higher than you normally can. You can extend your arms half your height above yourself during the jump. Thus, you can reach above you a distance equal to the height of the jump plus 1½ times your height.
THIS is more realistic and less crazy. Again, we really need an implementation of the ACTUAL rules, and we need the game to be less clunky.
