I mean could be a wyvern maybe it's a small dragon (?) and maybe you have to shoot the bullets at a specific point (a point in their neck for example)

• option 1 ~ they are dragon bullets, of course, like, hello
• option 2 ~ dragons do not exist, so... "what are we doin' here"

What kind of bullets are these so that it only takes 2 of them to kill a whole dragon???
