I particularly like this one.
Can definitely work for like a replacement to Shadow Crash and be the new version of Dark Void but have the same interaction as Shadow Crash with Applying Vampiric Touch and synergy with Misery to apply Shadow Word: Pain.
You can see a Dark Naaru as well. So this is more “Void” slanted to the Void state of Naaru instead of Old Gods. Which I am more of a fan of mainly because it fits the priest esthetic more so than the occultist angle does.
Other interesting ones that can work for Shadow are these as well.
