This is an attempt to define what players can and cannot do while jumping. Especially when it comes to strength.
Yan Zhi Cheng holds the unofficial record for the highest jump with both legs, reaching about 8 feet. This is assuming he had above-average strength and dexterity, so I will assign him a score of 18 for each.
A character with 10 Str can jump 1 foot. Every point in Str increases the height of his vertical jump by 1 foot. Jumping horizontally is used with Acrobatics, as normal.
So basically, feel free to have your Fighter with 26 Str and a belt of Giant's Str jump like freaking Superman. :)
I swear to all the gods, if one more person makes a snide comment on how its 'just a RPG,' not real life, I will find a way to make them pay.
Um...jumping was rolled into the acrobatics skill...how high you can jump is rather clearly defined in the game rules. Or are you saying that you want to reconnect jumping to strength as opposed to dex as it is now?
