The laws of magic are more like "really hard things we don't know how to do" than actual limitations.

Jafar and Amara simply allowed for themselves to wield the powers that they couldn't achieve on their own. So instead of using Cora's spell of Vipers eye, Chinera blood, and the heart of the thing you hate most to make someone "love" you, they could simply will it.
