Effect: - Prevents opponent from apparating into a designated area. This is not a duelling spell, but though very rarely, you can think out of the box and use this for duelling.(think of creating a range around yourself which the opponent cannot apparate into, if he is giving you a hard time during duelling, apparating and disapparating, or think of protecting your home and home's grounds from apparating dark wizards)

Spell Type: - Defensive, most often used to protect an area from apparating intruders.

Spell Block: -

Incantation- Potest Intoir, pronounced as poh-TEST eent-WAHR.

Wand Movement- A wave across the area to be guarded.

Willpower- Strong, Must be stronger than the will of those trying to get in.

Concentration- Strong, Must imagine an impenetrable wall around the area to be guarded.

Please note that there is also an anti-disapparition jinx, which is discussed below.

Effect: - prevents an intruder from disapparating from an area. This is more likely to be useful in duelling as you have effectively trapped the opponent or an intruder in a certain area if he has no other means of escaping. You just need to think out of the box for it though.(think using the Fire-Making Charm to create a ring of fire and placing the anti-disapparition jinx on the area to prevent the opponent or intruder from getting out of it, or think of using Brachiabindo or the Full-Body Bind Curse or the Incarcerous Spell, and then after removing the opponent's or intruder's wand from their person, place the anti-disapparition jinx on the area, effectively trapping them in the area)

Spell Type: - Offensive or Defensive.

Spell Block: -
