Need help calculating Jump

[RigaMortus]

I am making a Monkish character that has great Jumping abilities. I am just having some difficulties trying to figure out how to calculate his Jump because I have a lot of different items/feats that factor into it.

I have a PsyWar 1 / Monk 6

Base Movement: 30'
Unarmored Movement: 50'
Movement with Boots of S&S: 100'

Ring of Jumping (+30 unnamed bonus to Jump check)
Boots of S&S (+10 competence bonus to Jump)

Total Jump Skill: 55 (+11 Ranks, +2 Strength, +2 Tumble, +30 Ring of Jumping, +10 Boots of S&S)

I also have the Mental Leap feat.

Let's assume I take 10 on a Jump check. Where do I even begin to calculate what my Jump is?

Some things that confuse me:

1) Under Jump it states, "If you have a higher speed, increase th distance jumped proportionally". So if I had a speed of 50, that would be 2/3rds higher from a base speed of 30. So if I ended up Jumping 6 feet, 2/3rds of that would be 4, so the end result is 10 feet.

2) Do I also need to consider the extra speed from my Boots? In which case, that would be 100 feet which is 3 and 1/3rds the distances. So a 6 foot Jump would then be 20 (6 x 3 = 18 + 2 =20), correct?

3) Then I also have to consider the Mental Leap feat which states "You Jump twice as far or as high as indicated on your Jump check." When do I factor this in? At the very end? Does this override the 3 and 1/3rd extra distance I Jumped on number 2? In which case, it would be less (6 foot Jump x 2 from Mental Leap = 12 feet)? That doesn't make much sense IMO. Or do I calculate this in at the very end. So my 20 foot Jump from number 2 is actually 40 feet?

I need someone to write type up these steps if they could. Once I see them, I'll understand.

Let's say I want to do a Standing High Jump. I have a 53 Jump and I will be Taking 10, so that comes out to a 63. How high can I Jump?

Multiple multipliers add, according to the standard rules. (No wonder you're confused.) Your jumping distance is multiplied by 3.33 for your increased move, and by 2 for your psi-feat, for a total multiplier of 4.33. So, for example, a roll of 12 on a running long jump gives you a total distance jumped of:

5' (base) plus 57' (total roll of 67 minus 10) = 62' times 4.33 = 267'. Note that jumping distance is part of regular movement; your DM may rule that you can only jump that far if you have that much movement available (i.e. if your action on the round is to run, as your running speed is 400' per round), or that the excess distance carries over to the next round, which must include movement to cover it.

Happy flying! And may I be the first to recommend the Run feat.

[edit]Sorry, didn't see your example request. I'll leave my first one up for comparison ...

Standing high jump, taking 10: 1' (base) plus 6' (total 'roll' of 65 minus 10, divided by eight and rounded down) = 7' times 4.33 = 30'.

Thanks a lot. It looks much more difficult than how you laid it out. I think I understand now though.

Just one thing. Under Mental Leap it states:

Your maximum Jump (a function of your height) is twice as normal, and extra distance is not counted against your total allowed movement in the round.

So let's say I have a Speed of 30' (60 for a double move, 120 for a Run) and I manage to High Jump 80' up in the air. That means it eats up 60 of my movement, and the left over 20' does not go against me, so I can do the full Jump in one round. Correct?

[EDIT] Something else just caught my eye too. In the Jump chart, the very last type of jump you can do is "Jump Back". What do they mean by this? What is a "Jump Back"? Is this different than a Standing Jump or any other type of Jump?

Yes.

Oh man.

I think this is right:

Take you base move and calcaulate how far you can jump. That amount of distance is the amount not counted gainast you movement for the round (mental leap).

Now apply your multipliers. You may jump as far as your base move plus the amount that does not count against your base move from above.

Whew!!

Cool.

I'm trying to re-create a "Crouching Tiger" / "Bullet Proof Monk" type of character that Jumps from ground to rooftop, wall to wall, rooftop to rooftop, tree branch to tree branch. Well, you get the idea.

Yeah, Artoomis has it. I didn't have PsiHb handy & was going just by your description ...

I had a monk character whose jump skill I was maxing out. It's not really a powergaming type of thing (you're not going to break the game with long jumps), but it sure is fun!!

DM: There's a bridge across the chasm, but it looks very rickety.
Me: I jump the chasm ... (roll) ... Forty-five feet.
DM: Who the heck are you, Carl Lewis?

(I made a spreadsheet that let me put in a jump skill, speed, and height & would calculate the jump distance for each possible d20 roll, then printed it out at each level to attach to my character sheet. Those calculations are much easier when you pre-calculate than when you have to do them after you roll ...)
