Chain Armor Trim

The chain upgrade armor trim would be a magical upgrade armor trim that can only be applied to chain armor and would require some sort of magical chain item in place of a material on a smithing table.

What it would do is, when you hit a mob with a range attack (including thrown things, like tridents, snowballs, and eggs), it would shoot out a chain entity that pulls the mob closer to you if the mob was within a certain range that increases the more pieces of this armor you're wearing. The chain entity then despawns.

I want this to be added because it would add another upgrade armor trim and give players some incentive to get chain armor.
