Op Sword

This mod makes a overpowered sword! This sword comes with a ability that would make it a pretty good weapon, the ability is that if you right click it will summon lots of lightning and give you a high enough level of resistance that you won't be damaged by the lighting however people near you will! And if you drop the sword on the ground it has a 70% of summoning an minecart in chest, and a 20% chance of summoning a minecart with command block! If you want to play on singleplayer you just need the mod client side but if you want to use this on a server you need to have the mod client side and server side!
