I'll explain how the totem array works,
The first two are for your strongest element at the moment, so you can control it, then the others it's random,
There is also a bad luck guard for wasting emeralds at the altar, the first one is 4,500 emeralds, and at the beginning there is a quest that "if you waste 4,000 emeralds at the altar, then you get 5,000 emeralds", so everyone does it, and then you get one totem for sure, and you can choose which one it will be By strengthening one element of your titans more than the others,
The next limit is 45,000 emeralds, all the list is here.
There is another way to get a totem without emeralds, in the winter at the "Letter to Winter Claus" event, you can choose 3 items from the list and when it's January 1st, you will receive one of them! One of the options is "1 Lesser Elemental Spirit Summoning Sphere", if you're lucky of course
