Context: It's an ability for a character that has been transferred into an another world.
Quantum Armory
An ability born out of necessity to compete with other adventurers despite lacking the capability to use Magic. Magic requires training from a very young age to use it to it's fullest potential, however, since the user was transported into another world at the age of 18, she has lackluster magic abilities despite having very high potential. So she devised a different way to use magic. Being an avid fan of the FPS game genre and has experience in hunting back in her original world, she instead made a device that can summon amped military weapons and vehicles to aid her in combat. The device takes form in a wristband like device with a holographic screen that can be used to materialize various weapons, ammunition, utilities, vehicles, and even a simulated aerial support. However, unlike items she carries herself, items materialized by the Quantum Armory is slightly weaker and only lasts temporarily in combat, the length of time the items stay active depends on the items itself. Materializing these items requires "Credits" as explained below.
"Credits"
Credits are her manifestation of magic that she can use to "buy" weapons in the Quantum Armory. The more mana she has, the more "Credits" she can use to "Buy" weapons. More powerful items will cost more "Credits", small arm weapons are the cheapest to buy and direct aerial support are the most expensive.
What can be materialized:
Various small arms weapons like submachine guns, assault rifles, shotguns, grenade launchers, and many more.
Heavy weapons like anti-material rifles, heavy machine guns, and RPGs.
Automated sentry turrets capable of operating independently with commands given by the user. They automatically disappears once they ran out of ammunition.
Various utilities, like a lightweight physical shield, deployable one-way energy shields (which also increases the power of her weapons when shooting through it), radar sensors, additional ammunition, healing kits, and a power booster for her weapons.
Vehicles like motorbikes and jeeps.
Direct aerial support, this can range from summoning cruise missiles to a virtual military aircraft (an advanced version of an AC-130) that can bombard a target for hours on end. Summoning these items requires very large amounts of credits.
Weakness: Compared to magic spells, Quantum Armory is less efficient. She cannot summon Aerial support when indoors.
AP: 9-C+ by herself, far higher with melee weapons, 9-B+ to 8-A with small arms weapons, up to 8-A+ with heavy weapons, varies from 9-B+ to 8-A+ with sentry turrets, up to Low 7-C with aerial support. Can ignore durability via Overpenetration skill.
Durability: At least 9-C+ likely far higher by herself, Low 7-C with her various shields.
