The Iron Ring of Speed
I wanted to try making a mod, so here it is :D
All this mod does is add a ring to the game. To craft it, you need to place 4 iron ingots in a ring shape and then place a iron pickaxe in the middle. This will give you the Iron Ring of Speed! Right clicking on this ring will grant you 30 seconds of Haste V and will consume the item. You do get the 4 iron ingots back though, meaning you only need another iron pickaxe to remake it!
...and before you ask, this mod was created using MCreator. I haven't found any incompatibilities currently using this mod, so you can include this in your mod pack without my permission, just please give credit when due.
