As mentioned in the title, Customizable Armor allows you to make armor to protect your creations from damage. If the remaining protection is still here after damage taken, then the creation itself won't be destroyed. likewise, if damage taken is more than the remaining protection of the armor then the armor itself will be destroyed and the bullet/missle/Slug(Sphere)/Bomb/Rocket itself will move on to the next layer of armor(if there is no more layers of armor then the creation itself will take damage or get destroyed).

Modifications that can be made to armor:
Increase Protection: up to + 5 but also increases the weight of said armor
Decrease Weight: up to - 5000 but also decreases the protection of said armor
Dead Weight: Self Explanatory
