Magic Type Proposal: "Machina"

~Machina "Magic" Idea Proposal for the character Arc~

So my main idea for the usage of this relies heavily on the special type of "mana", equipment and preparation before combat. The usage for this would be focused on mid-range to long range support. Focusing on keeping targets at bay while keeping allies from dying. I'll split the idea into three sections; Equipment, Mana and Magic.

-Equipment: This is the main means of attack an support in combat. To begin on things are the weapons or firearms; first are two Enhanced Ruger P85s for mid-range combat in means of dealing damage. Next ebing the Enhanced semi-automatic sniper rifle, capable of hitting targets from 800m at max. The user is able to carry up to 5 different kinds of bullets or capsules.
-List of possible bullets and capsules
~Piercing, Healing capsules, immobilization capsules, elemental bullets, blast bullets, etc.
And lastly the a fully enhanced one time use rocket launcher, capable of creating a great explosion or another use of exploding into a great healing mist on allies.
With main load-out done, a few sidearms perhaps. I was thinking close range would be a means of last resort, so a combat knife capable of going up against tough opponents or disposable barriers, bombs or healing grenades. And then there comes armor, such as braces, padding, anti-magic armoring, communications, turrets, etc.
Though as this would be highly abusable perhaps a set let limit to what can brought into combat can be enlisted.

"Mana": So before going into the magic, I wanna talk about the special "mana" being put into place here. I was thinking of using metal scraps as a usage for the magic being proposed. Now these scraps or the ones being brought into battle initially metal plates would be used to manifest or create machines, tools, ammo, or refilling inventory for the user to use instead of the usual mana. So like a few examples, one slate can be used to refill one type of ammo or create an attack drone or healing drone with the cost for plates increasing depending on the wanting creation. As well destroyed metal scraps from drones or bost count as one scrap unless the target scrap is giant.

Magic: the main premise of this magic would be the likes of what was said in the mana portion but lets elaborate. The magic is focused on summoning/creating machines, ammo, or repairs based on the users amount of metal craps they have. The machines created would be advanced but most smaller in scale. Like the likes of drones, movable spy cam bots, detonation drones, healing bots, sentry turrets, ect. Or repairing machines, technologies if the user has enough metal scraps. This magic primarily involves the users conection towards tech, metals and machines. the more metal scraps the user has, the more prepared they will be. Certain drawbacks would be that the user does has limited uses and they can't carry a large amount of metal scraps as that would simply weigh them down during a fight.

And for a takeover, well basically call in a mech and unleash weapons like mad. Destroyed large machines such as these would yield a large amount of scraps.

Important note: The user would only be able to transfer destroyed machines or pieces into scraps if the majority of the remnants are there.
