The following list contains many encchantments and spells found in the series. I have done my best to include each spell's name, incantation, and effects. For some entries, you may have to look up the spell on your own.
I do hope that everyone takes advantage of this list.
Disarming Spell (Expelliarmus). This is how the Death Eaters can identify Harry in the heat of battle or in a chase. They seem to think it is his signature move. A relatively simple spell, it causes your opponent's wand to fly out of their hand, leaving them at your mercy.
Stunning Spell (Stupefy). This spell knocks your opponent unconscious. They can only be revived by the counterspell (Ennervate).
Shield Charm (Protego). This spellguards you against most minor hexes and jinxes. However, it does not protect against the Unforgivable Curses.
Summoning Charm (Accio *noun*). This summons the object you name. Just make sure you don't get hit in the back of the head by the object. It is very useful when finding lost things.
Patronus Charm (Expecto Patronum). This is the only thing that repels dementors. You cast it by thinking of a happy thought. Each person's Patronus is different. Also, not all wizards ever master the spell. It is not to be confused with the remedy for being with a dementor (chocolate).
Wingardium Leviosa. Makes objects fly.
Banishing Charm. The opposite of the Summoning Charm.
Alohamora. Unlocks doors.
Lumos. Lights the tip of your wand.
Nox. Puts out the light.
Imperius Curse (Imperio). One of the Unforgivable Curses. The (theoretically) least harmful of the three, it gives the caster complete control over the victim. It is possible to throw it off, but this takes a lot of work.
Cruciatus Curse (Crucio). Causes extreme pain. It is the preferred curse of torture.
Killing Curse (Avada Kedavra). As the name implies, this is used to kill people. The victim's last sight will be a flash of greem light. There is no blocking it. Only Harry is known to have survived. It kills instantly and without pain, leaving its victims unmarked except for the terror on their faces.
Morsmordre. Casts a Dark Mark into the sky. Death Eaters will place it over houses where they killed. It is everyone's worst fear.
Leg-Locker Curse (Locomotor Mortis). Sticks the victim's legs together, leaving them unable to walk. A great source of amusement for the caster.
Full Body-Bind (Petrificus Totalus). This makes the victim unable to move or speak.
Silencing Charm (Silencio). As the name implies, it silences the victim.
Levicorpus. A nonverbal spell, it hoists your victim intothe air by the ankle. Another source of amusement. (Use Liberacorpus, another nonverbal incantation, to undo)
These are most of the major spells that have come up already. As more are used, I'll add to the list. I do encourage you to look up new spells.
