This doubles the speed, and changes gravity from 0,35 to 0,1 on all vanilla arrows.
It also affects mods that use vanilla projectiles for their arrow types, like for example SPERG's ethereal arrows (they use the vanilla bound arrow projectile).

It does not touch any other values, so it should be compatible with most other mods.

I know there are other mods that changes the arrow speed, but for some reason they didn't quite cut it for me (and they overlooked bound arrows). So I made this mod. I made it so simple, that it can't go wrong.
