I think you are asking about count of total energies as we can add maximum upto 5 in one combination.
Please understand first thing you should club Switchword with same healing aspect in a combination.
Secondly, if you request VK GOLDEN SUNRISE× 3 then it is considered ro be 1 energy.
If you request for TOGETHER ×3 is also counted as 1 energy.
But if you request for GOLDEN SUNRISE TOGETHER ×3….or GOLDEN SUNRISE DIVINE LIGHT SHIELD ON ×3
It is also counted as single energy.
You can still add 4 more serums/energies.
ie,..A combination of two three or more Switchwords is also used and is called a Switchword phrase.
As a VK user serums are better and more powerful as these are combination of many energies also Switchwords energy clubbed in.
