It, if cast correctly, summons magickal lightning from heaven and black fire from hell. It is wise to contact spirits with high experience and knowledge to get their advice on casting it.
Casting Instructions for ‘Heaven’s Thunder and Hell’s Fire’
Before casting this spell, please note: It should only be utilized in times of great distress. This spell can be quite dangerous to you if used improperly. If you feel you’re not experienced enough, please don’t attempt to cast this spell.
Now then: to begin the spell, pull as much magickal energy as possible (without hurting yourself or getting dizzy/tired) out of yourself in a sort of bubble around you. Next, focus with all your might on 3 things: keeping your energy around you, black flames appearing in a circle around you, and a lightning storm over you. You may feel a rumbling feeling deep in your bones; that is because you might have not handled magick of the power before. Dont worry; if you have sufficient experience and know how all magick behaves, you WILL NOT be harmed.
The next thing you will most likely feel is heat all around you. Do not be alarmed. That feeling is the magickal black flames conjured up from hell. Since they have been conjured by YOUR energy, they will not affect YOU.
Now… what should happen then is the clouds above you’ll send a bolt of lightning down, making a cage made of lightning around you. That is the lightning shield; it will move with you in case you walk around. Do note, however, that illusion spells can still pass through, if they are powerful enough. If you’re trapped in an illusion the spell will fall apart and you’ll lose about 70% of the energy you used. The rest will return inside you. That is pretty much all there is to it, except the fact that the lightning shield will sometimes send outward modest bolts that hurt.
Again, do not use this charm for offensive tactics. It is not supposed to kill, just as an ultimate defense. Should you ever choose to cast this spell, I wish you all the luck.
