If Amaterasu and Chibiterasu become unable to use their Celestial Brush, usually because of depleting their ink, their Divine Instruments will disappear from their back, limiting them to attacking with mundane physical attacks until at least one inkpot regenerates and restores their weapons to full use. They can also be stunned by direct physical strikes (Amaterasu will only be stunned if she is not protected by at least one level of Godhood). Amaterasu may also become immobilized for a few seconds after launching an aerial Sub-Glaive plunge, as the blade will be stuck in the ground. Similarly, when launching the Providence Crystal, Chibiterasu will take a while to rear up, then release the crystals. During this time, he is vulnerable to attacks.
