Expelliarmos

The Expelliarmos spell is one used by sorcerers to disarm other sorcerers as well as non-sorcerers of their magic wands in the EMPATH: The Luckiest Smurf story series. The trick in using this spell is to use it before the other sorcerer uses it against the caster to disarm him. However, a shield spell could be cast to block this particular spell's effectiveness, though it must be well timed.

It is based on a similar spell used by wizards in the Harry Potter book and film series.
