As a paladin you can only imbue with Epiphany 2 Helmets:
- Falcon coif: Intricate epiphany (mlvl +2)
- Dark Whispers: Basic epiphany (mlvl +1)
And answering to your question, yes it worths it.
I don't have the coif yet, but I heard if makes a difference in reespams as rosha because of the silencers decreasing your mlvl.
What I do have is the dark whispers helmet. I put basic epiphany on it and distance, so I use it to kill bosses :)
Hope I helped with my answer.
