The level of Pet Warriors will provide many different benefits. Pet owners should upgrade their Pet Warriors to the maximum possible level. The higher the level of the Pet Warrior, the more reward tokens it will earn when it battles the Rebels. And, conversely, if the low level earns relatively few reward tokens, it's worth remembering that the low level will also cost you a lot of food for the Pet Warrior. Additionally, the higher the level of Pet Warrior the faster the Pet owner earns Reward tokens, which reduces the number of times the Pet Warrior joins the battle. Naturally, if there are still available foods and turns to join the battles. Continue feeding your Pet Warrior and completing remaining fights to gain EXP to aid in character leveling.
