Using one medium or small humanoid corpse whitch this spell consumes and transform into necrotic energy. Only pile of ash and items, clothing, armor, weapons etc. is left behinde.Black shadow of death floats and then fill undead creature you control in range making them stronger.

Choose two of these following benefits:

• Add Health equal to your spellcaster level (updates with your lvl ups withou the need for casting it again)
• 10 ft. of movement speed and jumping distance tripled
• Upon death this creature releases Death cloud with 5 ft. radius centred on it self, forcing everyone inside to make a Constitution saving throw or recieve 2d8 poison damage. Cloud acts as a Cloudkill spell.
• Stats improvement: you have 4 points that you can add to any stat but none of them can change for more then 2 points (so you can for example raise one stat by 2 and 2 other stats for 1 or two stats for 2 or 4 stats for 1)
• Increase proficiency bonus by +2
• Body is magicaly enchanted and if killed it can be used again for reanimation. (body can still be destroyed by spells like disintegrate)
• Profficiency in light, medium, heavy armor and shields (some undead already technically have these).
• Proffciency with simple and martial weapons (some undead already technically have these).
• Profficiency in Constitution and Strength saving throws.
• Profficiency in Athletics, Acrobatics, Stealth and Perception
• This creatures natural attacks count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage (claws, fist, bite etc.)

Spell last for 24 hours. If you will cast this spell on the same creature every day for 6 days, placing the same effect on it each time, effect then stays permanently fused with its body can not be dispelled or supressed by antimagic field.
You can cast this spell multiple times on same undead creature you control but each benefit can stay permanent only once.

Due to balancing you can only control up to 4 undead creatures with this spell benefits.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can choose one additional undead creature you control for each slot level above 4th.

I recommend to make notes on what day, time and creature you cast this spell. This spell aim to give necromancer and option between quality and quantity.
