Erase

Erase was transmutation spell that caused mundane and magical writing to vanish.

Effect
Erase removed writings of either magical or mundane nature from a scroll or from up to two pages of paper, parchment, or similar surfaces. It removed explosive runes, glyphs of warding, sepia snake sigils, and arcane marks, but it did not remove illusory script or symbols. Nonmagical writings were automatically erased if touched and no one else was holding them. Magic writings had to be touched. If an attempt failed to erase explosive runes, a glyph of warding, or a sepia snake sigil, the runes, glyph, or sigil became activated instead.

History
The spell was attributed to Netherese arcanist Raliteff in -675 DR and was originally known as Raliteff's strike.

Inscription
According to the Book of the Silver Talon, the ingredients for the ink used to inscribe erase into spellbooks were: one ounce of giant squid sepia, an ounce of acid, three dozen crushed caraway seeds, one chrysolite and one black pearl.

The gems would be dissolved in the acid over the period of two days. After this, the acid was heated in an elven-made bronze tureen with the seeds being added after it was brought to a boil. This would neutralize the acid allowing the mixture to be cooled and mixed with the sepia.
