I was playing OoT smashing things whit megaton hammer and I got this idea.I thought "SLEDGE HAMMERS!".So here you go.
Iron can be wood,gold,etc.
What it does:
Whenever you left click with it in your hand you can't move for 4 seconds,making it a bad fighting tool,but will destroy the blocks touching the one you clicked on.Think of it as mini TNT.
You can mine a bit faster.
It does several hearts of damage
It has a delay of 4 seconds before using.
Tell me if you like or dislike,and don't forget ideas =)
Sorry Andrew, but no. Like the others said, pickaxes can mine quicker than it. The only advantage is mining obsidian with it for 4 seconds instead of 15. Maybe you should try salt and potatoes. Oh wait, I already made that!
