jumping hight

[kyloss]

I hopefully have a simple question, is there a reason why the verticle hight for a jump is the same whether or not you are tring to just jump verticaly or jumping for horizontal distance?, ie it is the same dc to jump say 6 feet up as it is to jump 6 feet up and 6 feet out-you reach max hight at halfway out so a 12 foot long jum get you up 6 feet and out 6 feet at the mid point. is this just an error in the rules or has it been covered in the erratta.( my numbers are based off of memory but they are the same.

It's not an error - it's pretty much intentionally that way.

Note that your math is a little off. The DC for a vertical jump is 4x the height you're jumping. The height off the ground at the middle point of a long jump is 1/4 of the jump distance.

So, to jump up 6 feet you need to hit a DC of 24. You can do so by jumping straight up in your own square (a vertical jump, DC = 4 * 6 = 24) or by jumping out (DC 24, you travel 12', at which point you're 6' above the ground).

As for the reason you'd do one over the other, sometimes you won't have the required distance to make a long jump.

I figured my math was off as I said the numbers were from memory, but the hights are the same, And I just thought that it just didnt seem right to take the same dc (24) to go 6 feet up or 6 feet up and 12 feet out. just seems like verticle should be 3 times or something same amount of acceleration directed directly against gravity as apposed to a tanget 45 degrees in between should give a greater hight.

Except that your "acceleration" (I assume you mean in a running start) is horizontal, anyway.

How far can you jump sideways if you pop off a feather fall when you hit maximum height in a long jump?

The same distance you'd allow without the featherfall. What does the featherfall have to do with it?

Shouldn't make a difference. Feather fall makes you fall at 10' per second, so unless you're more than 60' in the air (requiring a jump DC of 240) you'll hit the ground by the end of the round, precisely as you would if you had jumped normally. You won't get a useful sideways glide out of it or anything.

Besides, I don't like velocity and accelleration calculations mixed up in my magic. It leads to bad places.

(Note: I'm no expert in physics; this could be a load of carp.)

It sounds like your theory is this: by reducing your rate of vertical descent during the second half of the jump, you should be able to go further horizontally.

I think, in theory, that's true. But I think the amount would be negligible.

On a 30' long jump, you're only 7.5' in the air at the apex of the jump.

And, as the spell itself says:

Feather fall instantly changes the rate at which the targets fall to a mere 60 feet per round (equivalent to the end of a fall from a few feet)

In other words, Feather Fall probably wouldn't substantially slow the rate you'd be falling over the course of a 7.5' drop, anyway.

So, Feather Fall might keep you "airborne" a bit longer, but not much...and thus, I don't think it'd give you much more length (certainly not 5' or more of length, which is the minimum granularity of D&D).

Note: if we start to get into the realm of super-human jumping distances, then it *might* start to be a factor.

Cool, thanks for working out the math/rules on that, guys! I love EN World

blargney didn't ask about increasing the length of the long jump, but moving sideways. To me that implies changing the direction of your movement at the apex of the jump. blargney, it would help if you clarify your question for us. Did kenobi65 answer the intended question?
