Normally you make simple rolls for basic actions against characteristics. I was thinking of allowing a bonus if a character has a related skill to such a feat. For example, jumping is Agility. A character with Acrobatics would get a +10%.
I was also thinking that some tests could easily fall under two characteristics, for example, again, jumping. Jumping could be Strength or Agility. I was thinking of allowing players to choose which of the two to use in such a test and apply the Characteristic Bonus of the non used characteristic to his or her % for success.
Thoughts?
