Skills, skills are what seperate Dragon's Crown from Street Fighter,. By Completing quests from the Adventurer's Guild and leveling up through the aquisition of of experience points, skill points are aquired. Purchasing and upgrading skills can only be done at the Adventurer's Guild. Each skill falls within a certain category and may require obtaining synergistic skills in the same category in order to improve it to the next level.
Skills fall into two Categories: Common and Class Specific.
Common skills are available to all classes.
This is what seperates the wizards from the elves.
