I figured I'd split this listing the typos and other issues for Deep Magic into its own thread so we don't unduly weigh down the product discussion thread for this book. Here's what I've found thus far.
Shifting Resistance (Sp): Each morning, you gain a resistance 5 to a type of energy, determined by a roll on Table 1-1: Random Damage Type. This resistance increases by 1 every three wizard levels until you have resistance 14 at 18th level.
Should be either 1 every two wizard levels until 18th or else caps out at resistance 11 at 18th level.
Feyborn Rod of Wonder
16-20 Target ages (1-50 on a d%) or becomes younger (51-100) by 1d20 years (Will save 18 half) for one week.
Missing a DC in front of the 18.
Muddled Rod of Wonder
11-15 Target believes its hands are turned into tentacles for 1 round, and it drops held objects (Will 14 negates).
Missing a DC in front of the 14.
Champion of Hell
This is really a flavor quibble for non-Midgard campaigns. Hell is LE in most campaigns, and antipaladins have to be CE. It's not strictly wrong, but it is a style mismatch. Champion of the Abyss would probably be better phrasing.
Special Cosmic Events
Other cosmic events can be predicted with a DC 20 Knowledge (arcane) check.
Should be Knowledge (arcana).
Divinations spells are cast as two caster levels higher, and augury and divination spells never grant false results.
Augury and divination should be italicized, assuming the intent is for those two spells specifically and not just divination spells as a whole. Also, “Divinations” spells.
Star and Shadow Casting (Feat)
Prerequisites: Caster level 1, Knowledge (arcane) 4 ranks
I'm assuming this is taken from a 3.5 source and was not correctly updated to PfRPG rules, unless the idea is to restrict it to 4th level or higher characters. Also, Knowledge (“arcane”).
Eclipses only last an hour or two.
Isn't this too vague? 1d3 hours instead?
A reference is made to the “16 commonly known varieties of ioun stones” on page 36 and then “Beyond the 17 best-known and most-often encountered stone,” (emphasis mine.) Which is the correct number? Also, 17 best-known and most-often encountered stone. Singular.
Marble Sphere Ioun Stone
An illusory glamour also switches the color of each stone to a different one, preventing knowledgeable opponents from identifying them.
Shouldn't this be based off of Glamered armor or weapons, i.e., not an automatic thing and with only True Seeing revealing their true color?
“Sky Blue Sphere Ioun Stone” and after
These entries are printed in a smaller font point than the other Ioun Stone headings before them in the section, the earlier ones printed at the same point as “Ioun Stone Spells” on page 36 and the latter ones the same, smaller point as “Cleric/Oracle Ioun Spell” beneath it. (Just insignificant formating bugs, but still, they're there.)
Slate blue Prism Grants bonus smite attempt, turn attempt, or 2nd level spell
I'm assuming this is taken from a 3.5 source and was not correctly updated to PfRPG rules, unless the idea is to restrict it to uses of Turn Undead and not Channel Energy in general.
Slate Blue Ioun Stone
Once per day, the energy in this stone can be used to make an extra smite attempt (such as smite evil) or an extra turn undead attempt.
(See previous note.)
(I've also got some personal questions about the prices for a few of the new Ioun Stones, but that's not an inherent issue with the text.)
I'm still happy with my backing the Kickstarter, but the printed book has a few issues. Hopefully we can all make the PDF the best it can be.
Post any other issues you find here. The Kobolds seem ready and willing to get fixes done ASAP.
