Read Magic states:
"You can decipher 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 or trapped 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."
Linguistics states:
"You can decipher writing in an unfamiliar
language or a message written in an incomplete or archaic form. The base DC is 20 for the simplest messages, 25 for standard texts, and 30 or higher for intricate, exotic, or very old writing."
So I'm guessing that with read magic, one can read cryptic, unintelligible, magical writings, but not ancient, or unknown languages?
Can we just remove read magic or just have it function like linguistics? I mean, the point of read magic is what? To make it so only arcane and divine casters can read or figure out what a scroll or activation word is? And it's a lvl-0 spell, meaning it can be cast at anytime, at any moment for free? Can we just make it a class feature?
