stars are for spell books and all stars have tiers so if you find a fireball book tier 1 star 1 vs fireball tier 9 star 4 is going to be a lot different also some books are unique it means only 1 also there are going to be 9 tier and 9 star levels also to level up tiers have to kill monsters no other way.
adventurers ranks: beginner, amateur, professional, senior, master, adventurer, legendary adventurer, the explorers, tier 1- their 9.
beginners are the weakest of the bunch just starting out cannon fauter, amateur starting to understand the basics just barely better than cannon fauter, professional getting the hang of it can be good members of a guild or clan still not the best but main fighting force of all places, senior good can be a head of a family or a medium position in a guild or clan, master strong can be a country official, adventurer strong could be 2nd or 3rd of a guild or clan, legendary adventurer powerhouses guild leader or clan head, the explorers absolute strength helps protect country's.
