Projectiles

I'm currently making an Accesory mod and i have one accesory that summons evoker fangs when you hit enemies, but the evoker fangs aren't a projectile, they're a simple entity. To summon them i used the block "execute command at <>" and insde i putted "/summon minecraft:evoker_fangs ~ ~ ~" and that's it, only issue is that the fangs deal damage to you aswell, so you can maybe make a projectile and in the procedure section enter the "When projectile hits entity" and then add that command to that, you will have a projectile that summons evoker fangs when it hits any living entity. Hope it helped dude
