A Mother's Love

A Mother's Love is an achievement/trophy in the first Bayonetta game that is unlocked by making sure that Cereza takes no damage.

Description
"Defend Cereza during the out of body experience, ensuring she takes no damage"

Guide
For this achievement, you simply have to make sure that the shield or forcefield generated by Bayonetta doesn't gets hit by the enemies. To do this, a recommended tactic is to stand a bit of a distance away (but not too far that they'll move towards her anyway) and make sure it's not in the enemy's line of fire.

If you're struggling, you can do this on Easy or Very Easy. If you're a nitpicking kind of player, it'll get frustrating to get it right until the end of the level or the game.
