Item's/Skill's Ranking System
Items and Skills have a ranking system which also makes use of the star/colour system of grading. For every star/colour added means that the item/skill is more powerful/effective.
However unlike talent grading, items and skills use the lunar cycle to grade the different items and skills.
For people below Rank 1, their items/skills only have stars and colours for their grading.
