Because why not?

Alchemy line
The Grappletech Alchemer starts like any other Alchemer on 2* and goes as follows:

• 2*: Grappletech Alchemer
• 3*: Grappletech Alchemer Mk II
• 4*: Grapple Driver
• 5*: Tractor Driver

Yes, I'm aware that the last one sounds like something else. Got a better name idea?

Stats
The Grappletech Alchemer line shares attributes with other Alchemers. Speed and clip size remains the same and so does charge time. The one attribute not shared is damage. Not only is it normal damage, but it shares damage with the Antigua line. For example, say Argent Peacemaker deals 47 damage against a Gorgo somewhere in the Clockworks. On the same depth with the same damage bonuses, the Tractor Driver would deal the same damage. This means that in the end, the Tractor driver will not be usable as a tool for dealing any major damage. It shines with its functionality which I shall now describe.

Functionality
This would be where Grappletech gets interesting. Remember how I named it Grappletech? You could also call it the new Volcanic Pepperbox. VPB was really cool once. Instead of knockback, it had... Knockforward? Your enemies would go towards you rather than away from you when you shot them, anyway. That's the idea of the Grappletech.

Regular bullets:
These remain the same in all incarnations of the Grappletech, except for the damage and knockback. They're really just any Alchemer bullet but instead of a status or high damage, they've got reversed knockback. The reversed knockback should be as follows:

• 2*: 1v
• 3*: 1.33v
• 4*: 1.66v
• 5*: 2v

What's a v, you might ask. That'd be the Knockback of Valiance, i.e. Valiance does 1v knockback.

Charge attack:
This one differs from star level to star level so I'll just list them individually.

• 2*: It's just a somewhat bigger bullet that functions like the other 2* Alchemer charges, but instead of splitting, it results in 3-4v something reversed knockback.
• 3*: Same as 2*, but the bullet now knocks enemies down.
• 4*: Same as 3*, but the bullet now goes straight through enemies and always disappears at the same distance.
• 5*: Same as 4*, but the bullet now slows down until it starts going backwards. When it starts going back, the knockback will still be towards the player but it will instead be something around 1-2v. It will knock enemies down again.
