Wands are the focus for most magic for most people

Wandless magic requires more effort for the same effect. 

The wand is as unique as the witch or wizard that it chooses, because wands can be considered semi-sentient in their own right.

Ash wand is particularly good when casting defensive charms

Phoenix tail feathers make for wands that are very versatile but might just decide to act on their own accord and bring their user along for the ride.

wand movement is one of the most essential components of any successfully cast spell. 

Almost all targeted spells require that your wand be pointed toward your target at the end of the movement

There are many different types of wand gestures

It’s important to note that one of the greatest limitations of magic is the intricacy with which each individual spell is cast. 

Forgetting or neglecting a single detail could be ruinous

begin by reaching for your power and feeling it flow steadily through you as you say the words and make the necessary gestures. A calm, sustained focus will be required as well.

Mending Charm: created around approximately 1754 by Orabella Nuttley.used it to repair the Colosseum. simply say the proper incantation and make the correct wand gesture while picturing the item as undamaged.it doesn’t require a great deal of power or effort for most repairs but it demonstrates how continuous wand movement works. 

Unlocking Charm: unseals locks both magical and mundane.known as the Thief’s Friend. brought to the Wizarding World by Eldon Elsrickle. the counterspell was invented by Blagdon Blay. It’s not required that you be able to see the lock, but in this case it must somehow be attached to the door or chest you wish to unlock, and you still need to target whatever the lock is attached to. The complexity of the lock or in some cases its weight can both be limiting factors to this spell’s effectiveness.
