Energy Binding

First, take out a glass bowl, and fill it with water. This is used to gather energy for the spell, but if you don't want to use the water, choose another energy source. Then, have the water reflect the sun or moon, and say:

"Solar flare, Lunar mist I call on thee this day Bring forth your light, strength and power, so cast this spell I may."

(Imagine the sun/moon energy flowing into the water)

Like I stated above, this is completely optional. Now, to form the barrier. Draw upon your energy source, and send it towards your target. Once you have reached them, attempt to have your energy surround them in a bubble. Then, say:

"Light, Earth, Spirits strong Leave 's presence forever long Let their powers cripple, and fail with dismay I hereby banish your magic on this very day! So mote/might/may it be."

Imagine the bubble drawing the energy from your target and all around him, draining him of magical resources. Continue feeding the bubble/shield/wall with energy until you feel you can release them.

WARNING: Use this with caution, there are currently no counter-spells to stop this. Secondly, there is a possibility your target can breach the barrier if she/he is physically touching a powerful energy source which has greater energy than the barrier itself. Best of luck, and blessed be.
