A mod that removes knockback from projectiles. Mobs never reaching you are boring. Things like bows and arrows, throwing weapons among other things even Shurikens from tinkers. Should have no knockback and not stop mobs from advancing towards the player. They already have range making these weapons have a little drawback by removing all knockback form them would be nice.
I bet there are other stats from such weapon types that could be tweaked like projectile speed or a delay increase before throwing towables again.
