Acrobatics (Strength)

Jumping, climbing, tumbling, back flips, and other similar things would fall under acrobatics. Depending on what your character is trying to do there are different DCs and modifiers to your roll.

Jumping

If your character needs to jump they typically require at least a 10 foot running start for a medium or small sized creature. Large size creatures require 10 ft more for every category beyond medium. Smaller creatures only need 5 ft, which is the minimum. Long jumps are easier than high jumps, for rolls and DCs please review the chart below. For high jumps the value will be for what is vaulted over, not how high they are able to reach with their hands. To get the reach take the high jump height and add 3 ft.

There are times when a creatures movement speed is faster than 30 ft. For ever 10 feet of speed above 30 a creature gains a +2 movement bonus to their jump rolls. Likewise a creature will gain a -2 penalty for every 5 feet of movement lower than 30.

Long Jump Attempted	DC
10 ft. long jump	10
15 ft. long jump	20
20 ft. long jump	24
25 ft. long jump	28
30 ft. long Jump	32
High Jump Attempted	DC
2 ft. high jump	10
3 ft. high jump	16
4 ft. high jump	22
5 ft. high jump	26
6 ft. high jump	30
7 ft. high jump	34
Circumstance	DC modifier

Strong headwind	+10
Mild tailwind	-5
Strong Tailwind	-10
No running start	+15

Climbing

While typically seen more as an athletic thing, for simplicity sake climbing has been added to acrobatics. Climbing can be initiated on any surface though some are nearly impossible to climb without gear or tools. Climb checks are also made at the end of a jump if they did not land with their feat to catch themselves. Creatures with climb speeds gain a +20 on all rolls for climbing since the act is second nature to them, but can fail in extreme circumstances. Review the table below for actions and their DCs, as well as conditional modifiers. Climbing is done at 5 ft per round typically. Hastily climbing makes the movement as much as 1/2 your base speed but take a -5 penalty.

Climb a knotted rope	12
Climb straight rope	20
Climb a surface with good hand/foot holds	15
Climb a surface with poor hand/foot holds	20

Combat Acrobatics

Rolling through, jumping, dipping, dodging, etc.. This skill can be used in combat to move out of threaten squares or occupied squares with impunity. For every 10 skill points in the Acrobatics skill your character gains +1 dodge bonus to AC when fighting defensively, and a +2 dodge bonus to ac during full defensive posture. Combat acrobatics are done at half movement speed. It also allows for the mitigation of falling damage to a degree. Below is a table detailing the use of combat acrobatics. If a move DC is failed then creatures gain an attack of opportunity against your character as normal. If a DC that is made to move through an occupied square fails, you are stopped before you enter their square.

A tumble check can be made to mitigate falling damage. For ever 10 points rolled above a 15 the fall damage is reduced by 1d6. Falling damage is calculated as 1d6 crushing damage for ever 5 feet past 10 feet of falling.

Action Attempted	DC
Move through a single creature's threatened squares	12
Move through a hostile creature's square	20
Circumstance	DC Modifier
Per additional creature threatening the same squares	+5
Difficult terrain	+10
Slippery floor	+15
Per size category larger than medium	+10
Per size category smaller than medium	-2
