Thread necromancy!
My campaign involves aboleth glyphs and ancient magic runes, so I've been wondering if read magic should be a spell available to PCs...
I was looking over comprehend languages and it states "This spell doesn’t decode secret messages in a text or a glyph, such as an arcane sigil, that isn’t part of a written language."
I'm assuming this is referring to the use of prestidigitation to create a wizard's mark, magic glyph traps/tricks the DM comes up with, or glyph of warding or symbol which state "The glyph is nearly invisible, requiring an Intelligence (Investigation) check against your spell save DC to find it."
So, hypothetically, a read magic spell could forgo the need for an Intelligence (Investigation) check? Or would it just identify the properties/meaning of a glyph once one is already aware of the glyph's existence?
