Before we start, no, I'm not stupid, I know that I need this, agility and magic together to level the playing field, but one at a time.
So, when I say resistance, I mean damage reduction (DR), i.e: the bullets are stopped by the dragon's armor. I obviously don't expect them to withstand anti-material rifles and such, I have the [That's my JAMMED] spell for those.
So, how could the dragon's armor withstand sustained fire?
Judgment process: I lay out criteria, in priorities, the answer that meets the highest, or the highest and the most of the other ones, wins.
- It should withstand the highest possible caliber, multiple times on the same spot. Of course, dragons are fast but I'm assuming a worst-case scenario.
- Light, it should be light.
Remember, graphene, though being able to disperse kinetic energy 10 times better than steel, is a reinforcing material. DON'T use it in itself, please!
So, I guess it's a duplicate, after all, [beep] Ok, so, I guess we could go with the mantis shrimp's club as a basis.
