Skill Tree Request
This is a request for a skill tree system. As far as a script goes, I haven't really seen any full-fledged Skill Tree Scripts.

Detailed Description:
Basically, I want a skill tree system that can operate with other systems like Sephiroth Spawn's EIS system, and adaptable to work with characters able to learn skills outside of the tree. As an example, let's say that a fire spell can branch into a firewall or fireball skill. If a person learns the 'wind' skill, an extra 'firewind' skill branch can be revealed if the game designer so includes it.

If possible, have it so you can have multiple pages of skills.
