I don't think just anyone can do it but Melissandre's shadow baby assassin was probably the most powerful magic attainable by normal humans. Since she's a Red Priestess and serves 'The One True God, the Lord of Light(™)' I don't exactly know if that even is magic. Technically magic is usually a left hand path thing, whereas the shadow baby demon was probably aided by TLOL. That raises the question which gods are true in that world, is it polytheism: old/new gods or the red monotheism, or a third option, henotheism.
INT. A CAVE
DAVOS leads MELISANDRE through the cave, bearing a lantern.
DAVOS: Strange that this Lord of Light asks you to work in the shadows.
MELISANDRE: Shadows cannot live in the dark, Ser Davos. They are servants of light, the children of fire. And the brighter the flame, the darker they are.
DAVOS holds up the lantern to bars that obstruct their way.
DAVOS: These weren't here before. They've barred the passage.
MELISANDRE: They can't bar our passage.
MELISANDRE has disrobed, arms outstretched, revealing a swollen, fully pregnant belly. DAVOS is shocked at this sudden change.
DAVOS: Gods protect us.
MELISANDRE: There's only one god, Ser Davos, and he only protects those who serve him.
