I think Assault Trigger are normally used by Kamen Rider Vulcan as default user because Kamen Rider Vulcan Assault Wolf are appeared before Kamen Rider Zero-One Shining Assault Hopper.

And the Assault Trigger are normally attached in Assault Wolf Progrise Key as default setting.

Yeah the Assault Trigger are really similar to Shift Dead Heat from Kamen Rider Drive because both Shift Dead Heat and Assault Trigger are used by Protagonist Rider and Secondary Rider.

I still wondering, can Vulcan still using Assault Wolf Progrise Key without using Assault Trigger when Assault Trigger are used by Zero-One? So maybe the downgraded version of Kamen Rider Vulcan Assault Wolf (without Assault Trigger) are same level as Kamen Rider Zero-One Shining Hopper.
