plz correct me if im wrong, but there is no way of knowing what a skill or spell leads too other than typing help skill_name and on the bottom it says "See Also: other related skills here"

well i was thinking of something like pro-requisite too see all the skills/spells that you can learn from learning the initial skill.

that would short down on the amount of questions asked by me or to me

For any class you can type allskills classname. example allskills cleric
This will list all spells/skills that classtype can get. You can then type prereq skillname and you can see what you need to get it.

Hope this helps.

The reason this is the way to go is because coding the other system would be difficult, messy, and the results would be messy to understand since there are multiple ways to achieve many skills. Thus we generally just go with the system described by Ezzence. At soem point though I will improve the output a bit to show what classes can get it when you type prereqs.
