So, I've been doing a few little drawings in the past few days (well, the first one is older, but-)
I figured out a few different ideas in terms of dps charms for priests, mostly just since I was bored recently... Sorry if any of these sound like mage charms, I was struggling to avoid cases like that. There might need to be a few balance adjustments on these, but hopefully they give you guys a general idea of them.

so, from top to bottom, we have:
Charm of Enchanted Fire
Every time Nourish is used, Holy Fire spreads to 1-2 extra targets at 75% of its current periodic damage
Charm of the Abyss
Targets inside Evil Land take an increased 5% of damage from all attacks
Charm of Poisonous Snow
Poison dust now adds a chilling effect, slowing cast and walk speed by 50%. Envenom cancels this effect
