I'm making an updated version of my Necro ideas thread from 2023 (https://forums.elderscrollsonline.com/en/discussion/633137/suggestions-for-necromancer-changes). One thing that ZOS has been doing lately is making skills require less micromanagement and loading them with multiple functions:
The Necro needs this same treatment.

Blighted Blastbones: cost determined by the highest resource.
(I have mourned the loss of Stalking Blastbones and I have accepted that fact that I'm just going to have to change my Necro)

Death Scythe:
As I have seen suggested on the forums, both morphs of the Necro scythe should get execute scaling. I agree that this would be a great and very needed addition.
- Hungry Scythe: should also apply life steal to all enemies hit.


Skeletal Arcanist/Archer: grants major sorcery/brutality when slotted on either bar. Increase the damage that their attacks do.

Shocking Siphon: while slotted on either bar grants major prophecy/savagery and increases damage done by 3%. The AOE remains on the ground even if the tether breaks early. *Increase the radius size.
- Mystic Siphon: the increased Health, Magicka, and Stamina Recovery persists even if the tether breaks early.
- Detonating Syphon: the damage AOE now sticks to you.

Flame Skull:
- Riccochet Skull/Venom Skull: applies burning/poisoned status effects. (Increase travel speed)

Spirit Mender: when active, applies minor cowardice to attackers.

Bone Totem: summons an effigy of bones up to 28 meters away. After 1 second, the totem begins fearing nearby enemies every 2 seconds, causing them to cower in place for 4 seconds. (Changed to allow both morphs to be targeted)
- Warding Totem: (Formerly Remote Totem) grants minor protection when standing in the area of effect.
- Agony Totem: afflicts enemies in the area of effect with minor vulnerability.

Restoring Tether: the effects persist on the player even if the tether breaks early.

Render Flesh:
- Resistant Flesh: (remains unchanged)
- Blood Sacrifice: consumes a corpse to grant you Major Courage (or Major Berserk) for 10 seconds.

Expunge: reduces the cost of all your abilities by 3% while slotted on either bar.

Bitter Harvest: when slotted on either bar, reduces your damage taken by 3%.


ULTIMATES:
Frozen Colossus: Unleash a decayed Flesh Colossus to pulverize enemies in the area. The Colossus smashes the ground three times over 3 seconds. Dealing damage applies Major Vulnerability to any enemy hit for 12 seconds.
- Glacial Colossus: does frost damage and stuns enemies on the second hit instead of the third.
- Pestilent Colossus: smashes the ground only once and does disease damage. Afflicts enemies with a pestilence that does damage over time.

Animate Blastbones: instead of resurrecting allies, this ultimate summons up to three blastbones to attack the nearest opponent. Summoned Blastbones are immune to being crowd controlled (other than by another ultimate). Reduce the cost of this ultimate to 200, down from 320, to make it more usable.
