How to gain Power Charges as Witch?

[iammyself]

Hello Folks,
I´ve looked through all the skillgems and support gems via ingame search and in the passiv skilltree... might have overlooked it, but how is it possible for a witch to generate Power Charges? Several skills of her take use of them but i cant figure out how to generate them.

Would be gratefull for help.

I use power siphon and profane ritual. It's pretty easy to keep up power charges. But their use is extremely limited. They no longer give any buffs directly but some skills can consume power charges.

Now i see it. thank you. iam curious if power siphon gets to the normal gem pool soon
