Alias? I'm not sure what you mean by that unless you're asking for their names, which is displayed above their HP. Baphomet was my back up since Amaterasu died.
All the currently shown himes I have are fully max break limit and leveled with 2 Croms for +40% HP to play it safe. Also using a SSR HP weapon from a previous event. My overall gear isn't really that great, as you can see from the 2nd screen shot I only just broke 30k recently with this party.
