Powergems are needed to fuse together to create elemental essences.

Each essence requires four power gems to be completed, and you need 4 essences to enter the castle.

This means you need 16 powergems

If you wish to create the 5th essence (the essence of balance) you need another 4 powergems, totalling to 20.

There is an exact total of 20 powergems in the game. If you want to build the 5th essence, you cannot miss a single one.
