The Layer Three spells, as they had been dubbed. The two strongest spells Erika commanded authority over.

Goshintai, and Hell's Gouging Sword.

The former, a marvelous trick of reality. Paying an enormous energy cost with this spell resulted in the creation of a temporary link between the mind of the user and reality, allowing images to pass from the former to the latter freely. In that sense, it could be seen as a way of working around the law of conservation of energy, a spell that found a loophole in the fabric of reality and exploited it. In other words, even if the cost of what was being projected would normally exceed the cost of Goshintai itself, or even Erika's maximum energy capacity, it could still be projected under the thrall of Goshintai. All the same, it had its weaknesses, as it was essentially just a "better" version of Devil's Projection at its core, and so was bound to the same principle of "something which currently 'is' cannot be projected." Not to mention the utterly absurd energy cost. While it was a fixed cost, a third of a witch's power on a single spell was so inordinate it was unheard of.

The latter though...the latter was the only solely "offensive" spell in the witch's arsenal. An arrow of light that would kill anything, from a man to a devil to even a god. If the Shinigami were struck with it, or a Kishin, or the great leader of all witches, they would not survive the attack. Even so, while in theory it was the "strongest" offensive spell possible, a strong enough being with a quick enough reaction time could negate it before it touched them. As long as it was blasted before it touched its target, its capability to be a "certain one-hit kill" would diminish. Not to mention the absurd energy drain caused by using it. Like Goshintai, it was something intended to be a last resort among last resorts.

She would probably need to use those more and more in the coming days. 

But for now...

"Fwah, two Go's, rest, projecting three Eggs, rest, and using Go a third time all in one day? If I hadn't restored at least something during those rests I'd be dry for the rest of the day. Sleepy..."

Such were the words of the witch who had earlier declared war on a god as she fell back onto the ground, closing her eyes.
