Vault-Extension-with-Gadget.

Some vault prompts can be summoned by having a gadget placed on the side of it such as railing vaults. Best performed by Ace's Selma and Goyo's canister but first discovered with Melusi Banshees. If it is impossible to place Goyo's canister on the desired location, you can perform a Floating Gadget Tech to get the Goyo placed. You can also get vault prompts from shields onto the Goyo canister if just the canister isn't enough, same goes for Kiba barriers.
