The Engorgement Charms

The Engorgement Charms (Engorgio) is a charm that cause the target to become bigger. If the caster attempts to engorge the target beyond a certain point that target will explode. Although the spell is safe to use on animals, it is not recommended until the counter-charm has been perfectly successful.

It appears as a circle of icy blue light glowing at the tip of the wand, much like a torch. Anything within this circle will expand bouncing and shivering.

Miranda Goshawk included this charm in the Standard Book of Spells, Grade 2, the third spell book. She also wrote about in the Book of Spells alongside the Shrinking Charm, which can be used to counteract this charm.
