Activation of corrupting fever LIFE COST Healp

Good day I have a corrupting fever scion and I want to update it, but I have a problem when activating my corrupting fever, since the cost of living (life cost) is very high. And I see that the build that I am following, does not reach that much life.

I attach the update of the build that I follow

and this is my build currently.

look at his amulet, there is your answer.

You only need to activate CF once if your fast enough, so he can just chain it with focus.

Yes brother, thanks for your help! - I don't know how I didn't see it xD
