# Step 8. Hero and Item Development ✔️ The systems for hero summon, transformation, promotion, and encyclopedia are to be released. Heroes have strong stats. You can combine several lower-level heroes to make them into a more powerful one. You can use more powerful unique skills and stats when transformed into a hero. In addition, by listing various heroes and collectibles in the encyclopedia, you can receive various in-game benefits such as character stat boosts, etc. Unlike other MMORPGs, in Klay Kingdoms the character levels don’t indicate a measure of growth. Instead, you can enjoy growth by accumulating experience points for the equipped items. You can earn revenue by selling other users the items you have developed. New users can adapt to the game more quickly by purchasing such items. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
