I don’t get why the fuck they made all that shit of how you can’t Volund the bullets without a heavy prince even though Jack was doing that with knives, stones and even the Big Ben. Simo Haya shouldn’t have that nerf.
Nah, you see when Jack was touching random things, they could negate the magic deity shield that normally makes them immune to random objects but they still keep their nature. The knives Jack didn't touch bounced off and the ones he touched pierced. But in the end, they're still knives. Heracles could still tank them, more or less. (Don't think about the clock face Jack pulled out of his ass.)
Meanwhile, Simo injects the premium 'skill.exe' into his bullets so he could get that tracking, armor pierce, aimbot that lets him shoot through walls and kill a hundred people in completely different directions with a single bullet. Totally makes sense.
