Read magic

Read magic is a widespread universal spell that lets one read scrolls and spellbooks.

Effect
By means of read magic, you can read magical inscriptions on objects -- books, scrolls, weapons, and the like - that would otherwise be unintelligible. This deciphering does not normally invoke the magic contained in the writing, although it may do so in the case of a cursed scroll. Furthermore, once the spell is cast and you have read the magical inscription, you are thereafter able to read that particular writing without recourse to the use of read magic. You can read at the rate of one page (250 words) per minute. The spell allows you to identify a glyph of warding with a successful Spellcraft check against DC 13 or a symbol with a successful Spellcraft check against DC 19.

Focus
A clear crystal or mineral prism.
