Echoes of Rememberance

Choose a pile of bones or a corpse of a Medium or Small Humanoid within range. The target becomes a Time Walker (see statblock).

On each of your turns, you can take a Bonus Action to mentally command any creature you made with this spell if the creature is within 60 feet of you (if you control multiple creatures, you can command any 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 on its next turn, or you can issue a general command, such as to guard a chamber or corridor. If you issue no commands, the creature takes the Dodge action and moves only to avoid harm. Once given an order, the creature continues to follow it until its task is complete.

The creature is under your control for 10 minutes, after which it disappears. The creature remembers its past and can choose to communicate with anyone, as long as it does not disobey a direct command.

Using a Higher-Level Spell Slot. You triple the duration of the spell for each spell slot level above 3.
