Erase removes writings of either magical or mundane nature from a scroll or from one or two pages of paper, parchment, or similar surfaces. With this spell, you can remove Explosive Runes, a Glyph of Warding, a Sepia Snake Sigil, or an Arcane Mark, but not Illusory Script or a symbol spell. Nonmagical writing is automatically erased if you touch it and no one else is holding it. Otherwise, the chance of erasing nonmagical writing is 90%.

Magic writing must be touched to be erased, and you also must succeed on a Caster Level check (1d20 + caster level) against DC 15. A natural 1 is always a failure on this check. If you fail to erase Explosive Runes, a Glyph of Warding, or a Sepia Snake Sigil, you accidentally activate that writing instead.
