Level 1:

He can only order someone's body to do something. 

He doesn't have control over their heart or thought.

To Order someone, he needs to exchange eye contact when his eyes turn purple.

When an order is given, it will be done until it is canceled or finished, or a new order that needs the last order to be canceled is given.

Example:

If he orders someone to kneel, then give him an order to walk. The kneel order is automatically canceled.

If he orders someone to cook food, the order is done after the cooking is completed.

If he orders someone to shut up, he will shut up indefinitely until he orders otherwise.

If he orders someone to yell, then add another order to do push-ups. The target will yell and push up at the same time. If he then tells him to stop, both orders are canceled.

Weakness:

This ability may seem overpowered, but it has many limitations.

The person he ordered has their will and memories intact! It's possible for them to retaliate after the order is finished.

Even with God's Providence, Malacai's body is weak compared to an average human.

He needs eye contact to give his order, which means he needs to be in close proximity.

Malacai is too handsome, and yes this is a weakness. Everyone who met him once will remember him, just like if you meet someone so beautiful or handsome that you feel like he/she shouldn't be a human.
