//  Item Option System
// Notes:
//  Awarded for crafters and their own base skill tree system

// Player knowledge structure
// CRAFTSYS[ SKILL_SCOPE ] = SKILL_LV

// ReturnVarID() takes the scope and finds out the skills on the group
// It'll fill the following variables:
//      @csys_attr → Available attributes
//      @csys_penalty → Penalty attribute array
//
//      use getarraysize(@csys_attr) to know how many are there.
// Players can active the bonus groups they want to use (in future, TODO)

// Max Level for base: 10
// Max Level for first tier: 5
// Max Level for second tier: 
// Max Level for third tier: 
// Max Level for ultimate tier: 1

// ReturnVarID( cr_id{, preserve} )
