This add on is made by Team Infinite Minds and Kodomo. This add on adds new 5 rideable clouds. Each cloud have different texture and speed. The lightning cloud drops a lightning bolt and when you get the lightning bolt you can summon lightning by just using right click/tap and hold when you equip the item.
