Not to burst your bubble or anything, but in case you haven't noticed, anytime OOO decides to implement a new weapon into the game, it's always been behind a low % drop rate from promo boxes. They've always been reskinned. And in the end nobody you'll ever meet will use them (because nobody has them). That is of course you're one of the rich players who can afford to buy it and toss it away.

So my point is, before you start suggesting new weapons for the game, remember what game this is and how disregarding the dev team and business that is behind them. You have to work around their laze and create reskins with slight changes.

Because that's the truth of the matter.

Scythe weapon might be able to work... But instead of making it its own line, how about have it split off from the 2* spur? Could share that attack style and go up to 5* and be pure shadow damage. Doesn't shoot projectiles like winmillion does, but has a charge attack that is similar (except it fires more like an obsidian carbine's bullet, with phantom zombies crawling instead of apocrean tentacles). Would prevent the spur line from being an early trap line.

I want to say make the calibur version deal elemental damage since you're firing off beams of light, but I don't think we need another holy elemental weapon... Piercing could work if we follow the gilded griffin's color scheme. Perhaps instead of being heavenly it could be more ancient god-esk, like "a weapon forged in the fires of heaven, these blades were given to its warriors who fought back the evils of the underworld".
Instead of beams of light it could fire 3 (shiny) bullets on its charge that can inflict stun (sword attack doesn't deal the status), that fire in a triangle pattern around the player and travel very quickly but only move 4 tiles. Sword has little to no knockback on the charge, however bullets cause pretty high knockback and the charge causes very high knockdown. At 4* you only have 3 bullets, but at 5* you get 6 in a sort of star of david pattern for the bullets.

And Paintool, the suggestions forum is for creative thoughts to explore various aspects of the game. Not a good place for pessimists or those bitter with the game. If such weapons get implemented they get implemented, regardless of how they are put in. Doesn't matter, it's fun to discuss potential additions to the game, and hopefully we can spark something on the developer's side that creates a change or addition.

I was thinking it would share the attack pattern of the Spur anyways, as that would make it not just another brandish/calibur clone. It deals normal damage, so I don't see why it can't split into something else (see: antigua lines).

We're in a video game. Use video game logic rather than outwards appearances.
