I just came up with an amazing idea for a mod that anyone is free to make. It adds in specialty enchantments for arrows. Yes I said arrows. You can stick a stack of arrows into and enchantment table. The number of arrows you put into the enchanting table and the enchantment you choose to enchant them with increases the experience cost. This mod also adds in a quiver. At first these quivers can only hold one type of enchanted arrows. But can be upgraded to hold 2, even 3 different types. And as long as you have the quiver in your hot bar you can press what ever key binding you set for this mod to cycle through the arrow types you have stored in it. The enchantments can be like,....
Fire Aspect: Set's target on fire
Ice Aspect: Gives target slowness effect
Blast: Arrow explodes on Impact
Blink: Teleport where ever the arrow lands. I know you can do this with ender pearls. But I thought this would be more accurate and longer distance teleport.
These are just examples. and can be expanded upon.
