Since an El can conjure a bow, hammer, axe, great sword, and shield then it leaves mace, sword, war horn, pistol, or rifle for the new weapon. Pistol and rifle feel mechanical and not elemental. So, I am hoping for mace, sword, or war horn. But then again I do love the Mes pistol and would have thought the same until I experienced it.
Since an Ele can only conjure these things whatever is not interesting about new and useful spells with perma equipment…
Also, mecha-cross class just sounds awesome.
Kinda like the idea of an engineer having an arcane specialty…
