Is there a cap on Z-Tokens earned from battles? (X-)Guardians can earn around 50 Z-Tokens from battles while Adventurers can earn 25. Additionally, your ability to earn Z-Tokens through battles is contingent on whether or not you have reached your reward caps. If you have reached both caps, you will not earn further Z-Tokens. Do remember that your gold cap is affected only by gold earned through battles, not by buying or selling items.
