Fantasy Westward Journey was a very popular online game where players could level up and unlock new skills and equipment. In Fantasy Westward Journey, characters were divided into levels of 90 and 100, and the summoned beasts that could be brought must be below level 100. This was because the summoned beasts in Fantasy Westward Journey were divided into different types, each of which had its own unique attributes and abilities. In Fantasy Westward Journey, the level of the summoned beast also represented their ability level. Therefore, only summoned beasts below level 100 could be carried by level 90 players. In addition, the summoned beasts in Fantasy Westward Journey have different potential points. These potential points can increase the level of the summoned beast and make it stronger. Therefore, only summoned beasts with enough potential points could be carried by level 90 players. In summary, the reason why level 90 players in Fantasy Westward Journey could bring level 100 summoned beasts was because level 90 summoned beasts already had enough levels and potential points to meet the needs of level 90 players.
