Idols are part of the core drop pool and will begin to drop at the Endgame. They scale entirely with juicing, and there is a static 50% chance that they will drop from the final Map boss to counteract randomness. The aim is not for you to rely on luck to find these, as they are meant to enhance the fun. As you progress further into the Endgame and apply more juice to your maps, you'll encounter more and more Idols, potentially obtaining several per map.
