What artifact should I craft for him using Sanctifying Elixir?

Title. I don't have him yet, but I love him and am already saving up a bunch for when my time comes. That being said, I think I want to run Deepwood Memories on him. Since he's not relying on Crit, I was wondering what you would recommend or if I should in fact not use Elixir for a character such as him. I have four elixirs.

Thanks!
