I have been searching for some particular boss for days on the Center.There is completely no spawns of Guardian Deity of Nature,Scion of Nature,the Omega Bosses and some other bosses.I wonder if it is just a probability problem so I was continuously killing mobs in the world just to seek a omega boss to craft my primordial but sadly I cannot meet any of one.My progress has been stucking for a while due to no primordial.Therefore,I would like to ask if there is any way that can solve for the problem and adjust the spawn rate of particular bosses since increasing the overall spawn rate may cause lagging to the computer.
Sorry for my bad English.
