About this Mod

This is a pretty simple mod that adds 2 potion effects: Size increase and Size decrease. THey do pretty much what you think, change your size. Also, when you break a block with the size increase effect, it will explode with an appropriate magnitude. What makes this mod unique is it uses minecrafts attributes instead of pekhui! There are also items for the potions. This was made using mcreator. Oh, and don't go too big if you're not looking for a game crash. Have fun destroying everything.
