It has been shown that Ais' Ariel can not only increase mobility and defense but increases offensive power as well.

Bell's Argo Vesta is also quite powerful especially if it is charged for a longer period of time.

Do you think that Ais' can use Ariel to buff Bell's attack, defense, and mobility if Bell used special equipment like Bete?

If she can then to you think that if she did it while Bell was using Argo Vesta that Bell might be able to hurt the OEBD?
