Yes, they can be augmented using our augmentation system. What do we know about augmentation so far? Augmentation is only available to Monsta with a level of 25 or higher. To upgrade a body part, you must burn STT and Monsta Cores that you can get from sacrificing a Monsta of your own, or defeating Jilaka, our in-game bosses. Kindly keep in mind, you can only play at the levels that correspond to your highest level body part. Otherwise, you won't be able to play at a lower level. Consider this when putting together your battle teams.
