Vein of BoneThe single attack ones seem out of place for a system that refreshes tokens every week.
I feel like I'm looking at a Diablo 2 Necromancer.
Armoured Dead - the way it is written the damage prevented to discharge is a combined total for all of the targets as opposed to tracked individually per target. Is this intentional?
Bone Prison not having a save is a little surprising.
Undying Hatred - are the created undead under the Necromant's control?
Animate Battlefield - same question as above.
Bonedeath is a little extreme.
You're right, high level stuff gets crazy.
Vein of CursesThere's no organization here...
A lot of these say they target creatures within distance of each other, is there a target limit?
Life Tap should mention that it isn't positive or negative energy so undead are healed too.
Blades Broken is extremely powerful....
Vein of FleshFoul Flesh Sanctity - What happens if a target leaves the range during the duration?
Vein of PoisonIs there a default time for secondary poison damage?
Needs to be finished (obviously).
Vein of SpiritLife Slipping Away - no save?
I'm not a fan of this casting system so I'll admit that I'm not scrutinizing it as closely as normal...
