The Greatest Magic Ever Misspelled:
Ars Magica 5th Edition Errata

Although we try to get everything right the first time, problems and typos have a way of slipping into everyone's publications. Ars Magica is no different. This page lists known mistakes in the Ars Magica 5th Edition rulebook and sourcebooks. This list does not include typographics errors (like misspellings) that don't impact the text meaningfully.

Thus, if you had a Risk Modifier of +3, and rolled an 8, you would get a Modified Effect. You could also subtract 1 to get a Discovery in addition. The effect of the spell is still modified.

The Transformed Folio
R: Touch, D: Year, T: Group, Level 45, Ritual
This changes all the pages of a book into those of a different book for the duration of the spell. You must touch both books when casting the spell, and because the spell is harnessed, you may end it at any time by concentrating. If the original book is damaged or altered, the contents of the duplicate will change to match it. Milvi occasionally use this spell to lend the same book to several different magi, or to communicate with each other over a long journey by linking a central book to a Redcap's travel journal. The spell also allows for vis boosting, so that you may copy a book using an Arcane Connection from wherever you happen to be.
(Base 1, +1 Touch, +4 Year, +2 Group, +5 intricacy; Boosted, Harnessed)

A Window of Singular Direction (p. 141): This is not wrong as it stands, but can only affect dirt walls. Increasing the Base to 4, and the spell level to 15, creates a version that can affect stone walls, which fits the descriptive text better.

Powers and Effects guidelines (pp. 48-56): Wherever a guideline mentions (level - X) or (magnitude - X) for the power of an effect, replace with (level + X) or (magnitude + X). One of the more annoying possible typographical errors.

The Great or Consummate Talisman (p. 70): Replace the contents of the insert with the following text:

Blending with Substance allows the magus to incorporate additional items into his talisman, as the Minor Virtue Great Talisman does for separate talismans. However, Inscription on the Soul does not allow the magus to attune new bonuses without working specifically on the talisman.

If a magus wishes to Initiate Consummate Talisman, then the magus can accept the required Ordeal.

Invocation Magic and Names of Power (p. 77): Add the following to the final paragraph: "although the combined bonus is still limited by Magic Theory."
