Invasion crystal skulls work the same as straw hat crystal skulls, but they are for non straw hat characters; Sabo, Whitebeard, Hancock, etc. There are certain times after you beat a clash where there is a chance you can encounter invasions from very powerful foes that have a chance of dropping those skulls. They can also be obtained from Rayleigh's bazaar for training points.
