Necromancy Savant

Beginning when you select this school at 2nd level, the gold and time you must spend to copy a necromancy spell into your spellbook is halved.

Necromantic Form

At 2nd level, your body becomes infused with the very magic of undeath itself, altering your mortal form. As a result of this transformation, you gain the following traits:

You don't require food, water, air, or sleep, although you still require rest to reduce exhaustion and still benefit from finishing short and long rests.
You no longer age.
You have disadvantage on Persuasion checks
You gain resistance to necrotic damage.
You have advantage on death saving throws.

 

Undying Legions

At 6th level, you draw upon your magic to reanimate and summon Undead creatures to fight for you. As an action, you can spend any number of spell-slots to summon a total number of undead equal to the total level of the spell slots expended. The summoned undead appear within 100 feet of you at a location you can see or directly within 10 feet of you. For example, if you expend spell-slots with a total level of 10, you can summon as many undead with a total CR less than or equal to 10. However, you cannot summon any undead with a challenge rating that exceeds your Necromancer level by more than one. Furthermore, you cannot have a total number of undead created by this feature with a combined CR that exceeds your level by more than one. If you summon more than your maximum total, you must choose which undead you control will be dismissed. A CR 0 undead creature counts as CR 1/4.

You can mentally command any creature you summon with this feature. The creature takes its turn immediately after yours. You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete or a new order is given. Creatures summoned through this feature last until they are killed or they are dismissed as a bonus action. If the summoner dies, the creatures will dissapear after 1d3 rounds.

Empowered Legions

Beginning at 10th level, you have immunity to necrotic damage, and your hit point maximum can’t be reduced. In addition, any Undead creatures under your control gain the following benefits:

• The creature's hit point maximum is increased by an amount equal to your wizard level.
• The creature adds your proficiency bonus to its damage and attack rolls

Master of Death

At 14th level, you have learned to infuse your undead with portions of your own mystical energies, empowering them dramatically. Undead you control gain the following benefits

They are immune to all effects that would turn or destroy them instantly.

They may add your intelligence modifier to their attack and damage rolls.

The damage from its attacks and abilities is considered magical for the purpose of overcoming immunity and resistance to nonmagical attacks and damage.
