The Immobilarus charm is a rather handy spell. When used properly, it freezes your target instantly, immobilizing them, hence the name. It is a relatively simple charm to learn and use. When you are suddenly or unexpectedly attacked, this will probably be your first and immediate response. With such ease and speed of use, there is always a catch: the effects of this spell wear off quickly, a matter of seconds. It is generally used not to disable a target and then run away or finish them off, but to buy a moment to gather your bearings and prepare your next spell. Your target will begin to regain movement in his limbs about five seconds after you cast this charm, so you should be at the ready to attack again or defend. The charm is used by simply pointing one's wand at your target and clearly pronouncing the word "Immobilarus." With some practice, you will be able to freeze multiple small targets at once with the same charm, but for now you should only try it on one target at a time.
