Every single character you use or face off against in BattleJack is ranked in a Star Level from 1 star all the way to 6 stars.
These star levels express how far the character has evolved and essentially how strong it is. Some cards will only have the ability of having 3 stars while others can have 4, 5 and 6 stars. Every single cards star level evolution is able to be attained through out the game tho the higher the star level the lower the chance of it dropping are.
To evolve a card to its next star level you will need to max its level out for that current star and then provide special evolution sacrifices, and sum of gold and also the same amount of current leveled star characters as sacrifices. Each star level has a set max level which continues to grow with each star level.
|Star Level||Max Level|
stance, to evolve a max level 5star Supreme Paladin Aldric you would need to provide max level 80/80, 2 Light Senteniels, 2 Dragon Mimics, 600k gold and also 5x other 5star cards (not including evolution cards Sentinels, ghostsetc)
