Idol

The Idol is a Forgotten Minion that can be summoned by merging a max level Golden Goose and Cultist when the Ancient Tablet allows. It can be used to spawn Gold Piles, with a 60% to spawn a lvl 1 Gold Pile and a 40% to spawn a lvl 2 Gold Pile, and has up to 10 uses.

The profit you can gain from merging the Idol will result in a minimum of 20 gold, a maximum of 57 gold, and an average of 32 gold. (This is calculated by subtracting the 15 gold from the Golden Goose that is lost in the merge and feeding non-max lvl Gold Piles as is, without merging them with Gold Piles generated from different sources.)
