Oh, one more broad one for animals I left out above. Rival Magic introduces the Mundane Quality Fins on p.84. This Quality should really be given to all the various "fish" (fish, whales, seals, etc.):
F&F p.66
LoH p.105
LotN p.97
ML p.58
ML p.60 (if seals should have it)
And then more I just rediscovered. There are more non-magical magical Powers (as noted in the previous post) in LotN p.18 (same Overrun as elephant), LotN p.23, and LotN p.97.
Yep. And the whole virtue from the base book p.41 probably needs to be rewritten to clarify the impact on requisites, something alone the lines of the virtue found in HMRE p.19, since the base book virtue really is the virtue from TMRE but integrated.
Some things that are not exactly errata, but which do need to be clarified:
A Magical Focus that is applicable to an enchanted device, does that apply when you are investing a power into the device even when the Focus does not apply to the power? If it does not apply, then why does the Confraternity of Roland (HoH:MC p121) intiate a focus in Swords?
Exactly what is needed for Sense Holiness and Unholiness to Penetrate a demon's Magic Resistance? The text implies it is easier than when used against and angel that is trying to stay hidden, but the language is unclear on exactly how.
How to handle the cases where the background of a character includes two different Magical Foci. For example a magus of House Tremere with Mythical Blood. There are several possible ways to handle this conflict, but no official way that I know of.
When Wizard's Communion is used, do all participants need to cast it as a regular spell or not?
A couple of things- 1) economics- this is spread over multiple books, but generally speaking most things cost more to make especially in terms of time, than they are worth. Which means an artisan spending making 2 seasons worth of good gets 2 seasons worth of income for goods that are worth less than what they make, even before taking into account the cost of raw materials. I understand that the medieval economy is messed up, but not that messed up.
Something missing is the bridge between artwork and industry- sure it takes a long time to make an artistic painting, but what about the craftsman copying the artwork? There is also a need for Aesthetic quality to mean more for artwork.
In a different line magic kin need to be better defined- it is currently unclear if they are supposed to have might or just a particular lineage of magical or mythical blood, or if they are something different (new mundane species with a realm connection?)
Vestiges (ROP;M) need a much clearer description, especially about how size and rating affect each other and whether they do- if I cannot over through a vestige because of its size can I use it for travel? Is there a minimum size to be able to enter a vestige for travel?
Also the degree of interconnectedness for boundaries needs better clarification. If a magical space is surrounded by a boundary which can only lead to one place then the degree of mobility through the magic realm is greatly constrained.
Lords of Men, page 60 in the "Kennels, Mews, and Stables Table", Stables section. The line for Excellent (Great Noble) stables has the numbers for the columns offset one to the left.
Currently the Quality is "Excellent (Great Noble) 40", Capacity is "3 per Horse", Maintenance is "12", Staff is "+2", and Living Conditions is blank. It should be Quality is "Excellent (Great Noble)", Capacity is "40", Maintenance is "3 per Horse", Staff is "12", and Living Conditions is "+2"
Lords of Men, p. 127, Effects of Mounted Movement table. The line for Walk/Amble or Trot is shifted one space to the left.
Currently the Penalty to Missile Attacks is "-1 (Horse's Size + 2)* + stress die", Falling Damage is "6", Extended Action Ease Factor is "+1", and Defensive Bonus (Optional) is blank. It should be Penalty to Missile Attacks is "-1", Falling Damage is "(Horse's Size + 2)* + stress die", Extended Action Ease Factor is "6", and Defensive Bonus (Optional) is "+1".
Additionally, the line for Gallop is similarly problematic.
Currently, the line reads "Gallop -6, (Horse's Size + 6)* + stress die, 12, +6, blank". It should be "Gallop, -6, (Horse's Size + 6)* + stress die, 12, +6". Commas separate column contents.
ArM5 p.109, the Experimentation results chart -- which comes almost straight out of older editions.
Unclear: if the experimentation modifies the spell (via side effect or modified effect) is the resulting spell level affected? E.g. if the experimentation results in duration dropping from D:Moon to D:Sun, does the spell level drop by 5 (for purposes of penetration, teaching etc.)? Note that this was not an issue in the older editions of Ars Magica (up to the 3rd) where there were no level guidelines, so it was natural to assume that the spell level did not change and you just got a spell more or less efficient than the norm.
Possible error: Discovery yields 15xps in an Ability, but 3xp in an Art. That's probably an error of the conversion from older experience systems, where 1 "old" ability xp was worth 5 "new" ability xps, and it should be 15xp in Arts too.
In faith and flame it indicates that the covenant of Bentalone was taken by Simon de Montfort in 1207, but Simon de Montfort was one of the few crusaders in the 4th crusade who bypassed the attack on the Byzantines and went directly to Acre, and did not join the crusade against the Cathars until 1209. In 1207 he was still engaged in arguing the distribution of his father's estates following his death.
Finally found what I had a vague note on:
MoH p.84: Eyes from the Wizard Torn uses base 3. However, on page 49 there is a base-5 guideline for "remove human body parts from the target... These parts are normally functional..." which it seems is the actual guideline used. After all, the eyes are still functional, and the spell relays what those distant eyes see to the caster. This would make the spell Mu(In, Re)Co(Im) 25. This level would also need to be corrected on p.82 (Marcus +45 years).
Possible errata in Ancient Magic
"Finding the locations of these relics and sites to help break the Limit of Vim"
I think "Limit of Vim" should be replaced with "Limit of Vis".
“Existence of The Engima of the Sons of God: Order of Hermes”
I think “Engima” should be replaced with “Enigma”
Page 70. Insert. Line sixteen.
“Location of the second volume of The Engima of the Sons of God”
I think “Engima” should be replaced with “Enigma”
“(Base 4, +1 Touch, +1 Conc, +2 levels for Penetration)”
I think it's missing +3 levels uses/day

I think it must be

“Virtue: Ceremony

TC&TC p80:
"These flaws are designed by Ferie jinn characters."
Unless Atlas Games employs some very unusal game designers I strongly suspect that should say:
"These flaws are designed for Faerie jinn characters"
HoH:MC p.95 (Vim): This was written pre-errata to match the old MuVi rules. You can see this with the note about durations matching the old MuVi note about durations. This paragraph should be adjusted to align it with the post-errata MuVi rules, probably using essentially the same new language like it uses essentially the old language.
Cov p.96: The Scribe's Touch should be ReAn, not PeAn. Certainly Perdo could be included if you want the bits to be disintegrated. However, just as the core book explains about Rego v. Perdo for sharpening a sword, sharpening a quill should likewise fall under Rego. Processing an animal produce is base 3, so the base should rise from 2 to 3 and the level should rise from 3 to 4.
ToME p.55: The Carnivorous House is missing +1 Touch in the calculation, so it should be ReHe 40.
I would just like to see Wizard's Boost cleaned up/clarified. There was a thread. It got bad really fast.
As written, it's non-functioning legacy.
Just noticed this one tonight, and I am genuinely astonished it's made it this far without some munchkin trying to use it to overrule the very clear rules on gain limits in chapter 10.
ArM5 core, page 71, middle column, first paragraph under the "Library" heading:
Summae have a level, and once a character’s level in the subject of the book exceeds that level, the book is no longer of any use.
"exceeds" should be replaced with "equals"; the current phrasing implies that e.g. a Level 4 summa is useful until a character hits a score of 5 in the subject.
This one is more complex. There are two options. The far simpler one is to edit the core book's rule (and I think one magus who's been written up, but I'm having trouble finding that one). The other is to edit a great many magi who have been written up to align with the core rule. That rule is that Spell Mastery Abilities are supposed to have specialties, and there is an example where they do, but for the most part magi have not been given specialties in their Spell Mastery Abilities. (The options that are chosen are akin to choosing a new alphabet with each level of Artes Liberales, but Artes Liberales still gets a specialty.)
Choice 1:
Core book, p.62: Change "Each Ability you select for your character should be assigned a specialization" to "Each Ability other than Spell Mastery you select for your character should be assigned a specialization."
Choice 2:
Add specializations to every Spell Mastery Ability for every magus that has any in any supplement that includes them.
.
While on Spell Mastery, it hasn't been given a category, and that category can be vitally important, such as with Becoming. On the bottom-right of p.86 in the core book it should be given a category, probably Arcane or its own category.
Nowhere in A&A is it explicitly stated how many seasons a work of art (Thing With Aesthetic Quality) may be studied. I've always assumed once, like a tractatus that doesn't necessarily require literacy, but it could stand to be clarified.
Edit: This isn't strictly errata, but while we're at it, A&A could stand the addition of some works of art to Appendix A, or an extra Appendix with some historically-important works of art. As a prominent example, the Odyssey is among, if indeed not the, most enduringly influential work of vernacular literature of the entire Western canon (see this BBC poll); surely it deserves an Aesthetic Quality and accompanying Source Quality for Craft(Poetry)? Or the Acropolis of Athens for Craft(Stonemason)? Or...I could go on. But I think it would be a valuable addition.
Hell, bundle it with the existing Appendix A (and for fucks' sake make Euclid's Elementa a summa, the man deserves it) and release it as a web supplement, like the Book of Mundane Beasts. Throw in a couple craft manuals and maybe Royal Armouries Ms. I.33 for bonus points.
