Battle Ward

You surround yourself with a magical ward capable of fending off attacks. This ward begins with a maximum of 11 temporary hit points. At the start of each of your turns whilst you maintain concentration on it, it regains 2d4 temporary hit points (up to its maximum), even if it was reduced to 0.

This ward does not prevent damage from the Magic Missile spell, or spells of sufficient similarity.

When cast at higher levels: When you cast this spell with a spell slot of 3rd level or higher, the maximum temporary hit points of the ward increases by 5.
