The first among the large Ball-type enemies, Mother Bits are like a middle step between the Bit Ball v2 and the Blast Eye, but that doesn't change the fact that they are relatively dangerous. Aside of the basic Laser attack, it also can use Electromagnetic Laser, a Lv. 2 Stored Attack, so make sure to pay attention to whenever they try to attack your Reyvateil with it, and heal immediately afterwards.
