Hello Players of Idle heroes. One of the main problems that beginners of the game idle heroes have is to decide whether they should keep a particular hero or convert them to fodder. Now, I have seen some beginners sacrificing their good heroes for fodders and getting almost very less in return. This guide is made for those beginners who do not know which heroes they should retain and which ones they should not.
By a thumb rule, do not fodder the Dark or the Light heroes of the game. The reason is that these heroes are typically rare and also more valuable to players than their values as fodder.
