crossbows is a mod that adds another weapon for ranged attack, so in addition to the default bow, we can use up to 15 crossbow variants, with which we can shoot up to 9 arrow variants.
There are crossbows made of various materials, as is the case with arrows, although the latter also have special variants, such as explosive, fire, spectral and teleportation arrows.
With a crossbow we can always shoot arrows of the same material as the crossbow, or inferior materials, that is, with an iron crossbow we can shoot iron arrows, but not diamonds .
