Violent Rebirth

You raise up to 4 creatures from the dead that you can see. You can raise a challenge rating 6 or lower with this spell. The spell can only raise those who have died within the past hour. The raised minions are mindless, they can only act out your will. On your turn you give them an instruction to follow on their turn. The creatures remain under your control until you disspell them or until they die, again.

When you cast this spell as a 4th level or higher you increase the challenge rating of the creature you can raise by 2. You also increase the number a raised minions by 1.
