Where to get an HFTotem as Scion?

Hello,
I'm playing a scion class for the first time and I'm having trouble getting the gems to start. I usually buy them from the dealer. Can these only be found in game or can I only get them by trading with other players?

Thanks and Greetings

ist it possible to buy it by a Dealer later Act 2, 3 4 etc...?
Or is it possible to start a new CHar (witch) till lvl 4 and give it the other char through stash?

ask in chaT anyone will buy u the gem/gems u need lol

Thanks for the hint. I forgot how easy it can be. I got one now ^^

in act 6 u can buy every gem after u beat 2-3quests}
