Elemental Tridents

You could upgrade tridents in the smithing table for different effects. There could be a dark trident that has daggers floating around it, and when you swing whey will fly in that direction about 5 blocks and come back. Also, there could be a gravity trident that gives you a jump height buff and when you swing midair you fall down quickly and create a shockwave effect when you land. It could also pull entities toward it when thrown. Those are the ones i thought of but if it were to be added i would hope there would be more.
