[This is a pretty random idea that just came to me, i have never seen or heard of this being done before, the mc is a projectile, an arrow, bullet, or even a fireball, this idea is pretty vague but the premise is that he is a projectile, and the more he is used the stronger he gets, should use a status panel though so we can easily track his progress, also he can multiply and make copies of himself since he is basically ammunition.]
(Message me when you make one or find one simmilar)
