Junior’s power will increase according to their step. When Junior gets a lot of EXP and reaches their Step-Up limit of 10, Junior has about 80% of the power compared to the Hero NFT. Finally, if Junior wants to have 100% of the power equivalent of a Hero, they must be ‘promoted’.
Junior NFT will be able to find the [Jr Promotion] button in their profile. This button is always displayed regardless of Junior’s Step. In other words, it is not impossible for Junior to challenge his promotion even when his step is low.
Promotion is the only way Junior can be turned into a hero, and once he passes, Junior will finally become a true hero NFT. Of course, you can decide when your junior will be “promoted.” This is because the probability of successful promotion depends on the junior’s step. A junior who has grown to Step 10 can pass the promotion with a 100% chance, but some juniors can also find a shortcut through a low probability.
Junior’s promotion requires special items. It’s a “promotion scroll.” You can check the number of promotion scrolls your junior requires when you challenge a junior’s promotion. It has nothing to do with the level or step, and it will depend on Junior’s rarity.
