Personally these abilites both are so underwhelming and better replaced with other abilites that i think a full rework should be done on both. Now im only talking about the mentioned morphs as the other morphs i think would be better served to be made for dps and im a tank main so id leave it to dps necromancers to decide what changes to those morphs should be. As for the mentioned morphs, i think that firsly unerving boneyard should be changed to be a 20 second on self aoe dot that applies major breach for 4 seconds called unnerving presence while the agony totem should be called instead i think something like instill fear and also be a on self aoe also for a 20 second duration and a burst of frost dmg every 2 seconds while also applying minor vulnerability and minor cowardice to enemies hit by the fear effect for 2 seconds after each hit meaning if you hit them with each burst even if they are CC immune, they get constant minor cowardice and vulnerability.
The reason for these changes is their radius is small and their duration being so short on top of having negligable effects that are better recieved from other abilities with the boneyard especailly being just a far worse version of razor caltrops that ends up costing too much resources especially with how frequently you have to move and replace them when they end after just 10 seconds with i wanted to make these abilites feel unique and different to the better versions of themselves like razor caltrops while also leaning into the kinda them of necro tanks where they are meant to be basically classic style deathknights rocking around with an unerving aura that instills fear in any who have to face them while reducing their defenses to nothing with their frost and necrotic energy that rend their armor and weapons just as much as their spirit to fight.
