Volcun's Animate Dead

This spell creates an undead servant of challenge rating 14 or lower. Choose a pile of bones or a corpse of any size within range. Your spell imbues the target with a foul mimicry of life, raising it as an undead creature. The target will rise up from where it was, with a dark purple aura flowing through it as it becomes a soldier of your undead army, the strength will stay the same with the same skills and hit points.

On each of your turns, you can use a bonus action to mentally command any creature you made with this spell (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). 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.

The creature is under your control forever even if they die, you can use a bonus action to summon your stored soldiers and choose how many to summon at once, if one of your creatures dies, you must make a concentration check, on fail they will leave the battle, on success they will revive at full strength.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the challenge rating of the creatures you can raise goes up by 4 each level
