I don't know if anyone's made a suggestion and this is the first time I make a suggestion.
==Prolougue==
I have nearly all the Brandish swords, except the Cautery Sword line; and I have almost all the Alchemers except the Nova Driver. So I thought about the Nova Driver line and I don't see a Brandish or Bomb that carries the characteristics of being a pure Elemental damage weapon. The only Pure-elemental sword I know and have is the Divine Avenger, but I don't often use it despite the decent UV I got from it (Medium CRT). So I thought of suggesting a pure-elemental brandish to have more variety and basically have a sword that goes with the Nova Driver. So this is the Brandish I thought of suggesting, I call it the Starsabre line.

Alchemy Line: Brandish > Staredge|3* > Shining Staredge|4* > Starsabre|5*
==Description==
Staredge: "A Brandish turned into a sword of light through Owlite Alchemy Technology"
Shining Staredge: "A focused blade of light crafted with Owlite and Spiral technology. Its bright enough to wander around in Candlestick and focused enough to slice a Rocky Core in two."
Starsabre: "This luminous sword is a creation of the technology of the Skylark's laser cannons and decrypted Owlite textbooks about Alchemy retrieved from Candlestick Keep. It can cut with the force of a thousands suns, and illuminates with enough power to ward off Grimalkins."
==Attacks==
Normal Combo: Same as all the other Brandish lines.
-What-if combo 1: Spur-line, including the thrust but no blade beams like the Winmillion (Unless its at 5* but that's tentative)
-What-if Combo 2: A wide, Troika/Sealed Sword-like (outside) slash first, then an inside slash (last slash of a Brandish combo) that thrust the player forward by one space, and finally a thrust (Last attack of a toothpick combo) that thrust the player by 2-3 spaces.
Charge Attack: Brandish Explosions like the rest, they are white-colored (Like the Supernova's shots).
-What-if Charge attack 1: Dash attack as if making the second blow with the Warmaster Rocket Hammer and deliver a slash forward with long reach and does heavy damage.
-What-if Charge attack 2: A blade beam that gets wider as it travels, like the blade rockets shot by a Divine Avenger except that its a cutting wave of light.
==Epilouge==
Okay, first of all, I doubt the devs would make the 5* that hax enough to ward off Grimalkins in Candlestick (it would be nice if that was true!). Second, the what-if combos and charges is mostly to try being different than to be the same-old Brandish. Finally, what I had in mind about its elemental damage is for it to be PURE elemental like the Rocket Hammer from the expansion and be fast (Flourish/Cutter/Spur Speed??? It is a lightsabre afterall) to make up for its lack of normal damage (Without normal damage, it wouldn't do much damage on Gremlins, Beast, or Vog Cub users in LD). The name "Star" is to go with the idea of Nova Driver being a gun that shoots with the "strength of the stars themselves".
Anyway, that's all I got to say as an epilouge for it.
Trivia: Starsabre is actually a reference to the Star Saber in Transformers: Armada. It is consider one of the most powerful swords in all existence in the Armada universe, and it can slice through anything.
Looks too Spacey.
But I'd Vouch for a Pure-Elemental Brandish.
