Compendium Arcanum Volume 2: 1st-Level Spells continues where volume 1 left off! This book includes 70+ pages of 1st-Level spells for the Pathfinder Roleplaying Game, now with Heightened and Diminished effects!
A multi-variable spell is a spell which, once learned, you can cast as a spell one level higher or lower than the original spell. This mechanic was first introduced in Monte Cook’s Arcana Evolved. Multi-variable spells give spellcasters great flexibility and so Tim decided to begin by adding the Heightened and Diminished qualities to Pathfinder spells.
So, in addition to the normal Pathfinder spell details, you will see one or two new bits of text, specifically, either a “Diminished Effects” line, a “Heightened Effects” line, or both. This is the first book of a set intended to include all spells from the Pathfinder Roleplaying Game Core Rulebook, Advanced Player’s Guide, Ultimate Combat, and Ultimate Magic, now with heightened and diminished effects.
DIMINISHED EFFECTS
This section describes changes to the spell if it is cast using a slot one Level lower than normal. You must be able to cast a spell at its regular Level before you can use the diminished effects. If you use a diminished effect, treat the spell as one Level lower than listed for purposes of spell slot used, saving throw DCs, magic item pricing, and so on. Spells that are 0-level (or 1st-level alchemist-, paladin-, or ranger-only spells) have no diminished effects.
HEIGHTENED EFFECTS
This section describes changes to the spell if it is cast using a slot one Level higher than normal. If you use a heightened effect, treat the spell as one Level higher than listed, for purposes of spell slot used, saving throw DCs, magic item pricing, and so on, regardless of what Level slot you use. Spells that are 9th Level (or 6th-level alchemist-only spells or 4th-level paladin- or ranger-only spells) have no heightened effects.

UPDATE:
The new pdf has an errata. This has made magic missile's diminished form non-broken and cleaned up and yes, the balancing of the most significant offenders regarding balance has been taken care of. Most, but not all, mind you. The problem still remains that all of the diminished spells, as cantrip-equivalents, can be cast infinite times per day. The interaction with other components of the system hasn't been improved either, making it remain a problematic system to plug into one's game. Hence, I do not consider the changes made enough to provide a full revised review of the installment.
This installment of the Compendium Arcanum-series clocks in at 80 pages, 1 page front cover, 1 page editorial, 2 3/4 pages of SRD, 1 page advertisement, leaving us with 74 1/4 pages of content, so let's take a look, shall we?
So what is this series about? In a nutshell, the compendium arcanum-series takes the concept of 3.X's Arcana Evolved for the option of heightening/diminishing spells and translates that to PFRPG. This means a spell can be cast as one level higher or as one level lower. The series covers all spells from the core-book, APG, UM and Ultimate Combat. If a class has no level lower (i.e. no cantrip slots), you can't cast the diminished spell and the heightened effects require you to be able to cast the heightened spell level - obviously preventing classes from casting a heightened spell that would e.g. be 10th level for a full caster or 5th level, for a paladin, to give you two examples.
So what do these modifications do, exactly? Well, for one, we receive de/increased durations - downgrades to rounds/level or upgrades to e.g. hours/level can be found herein - and especially the latter escalation is pretty nasty - when abundant ammunition can easily be made almost permanent, the rationale behind NOT doing that for every military ever to conserve ammunition suddenly becomes pretty problematic. Conversely, longer air bubbles and more creatures affected render the spell much more useful. Choosing the sound of an alarm or alarming more creatures adds a cool level of flexibility to the spell.
Other modifications influence the range of the spells and e.g. adding commands to animate rope, including movement and climbing makes for great ideas. Other spells receive a better action economy or add descriptors in heightened effects for new options. When the pdf goes for an extension in breadth rather than for numerical escalation is when it shines. On the downside, e.g. burning hands not only increasing the reach to 20 ft. but also adding the "shaken" condition may be a bit much - also, the wording is odd, with the text specifying "action" instead of turn. Indeed, here and there, the new effects do not properly modify the base spells - the heightened effects of command, for example, get rid of the language-requirement, which should thus eliminate the language-dependant-descriptor from the spell, which it RAW doesn't.
True Strike's heightened/diminished versions constitute an example for classic numerical escalation - the heightened increasing the bonus to +30, the diminished decreasing that to +5. On the plus-side, some spells have been merged into one component entity and this is noted - usually, these tend to constitute the better examples of design herein. Magic Missiles provide additional missiles at higher levels, whereas the diminished version only provides one close-range missile at 1d3 damage.
Conclusion:
Editing and formatting are very good, I didn't notice many glitches - quite a feat in a book of this size. Layout adheres to a printer-friendly 2-column full-color standard and the pdf comes with massive, extensive bookmarks as well as copious hyperlinks to d20pfsrd.com.
Timothy Wallace is a competent designer and this pdf very much showcases a couple of his strengths - the instances wherein the spells go into the breadth are downright glorious in very subtle, interesting ways. That being said, this installment, alas, is also one of the worst examples of subtle power creep I've seen in ages. Beyond the added flexibility the spells offer and the one or two examples that can potentially break in-game logic, which can admittedly be ignored, the pdf fails to address a significant problem, one that imho is rooted in 3.X design-philosophy. See, in 3.X, cantrips and the like adhered to the same rules as full-blown spells. In PFRPG, they are NOT expended upon being cast. Beyond the massive added flexibility, this utterly ruins any semblance of balance one can assume - take true strike: Infinite +5's, with only action economy as a balancing factor, this definitely goes beyond what a 1st level character should have at his disposal. Color Spray would also be an offender in that regard and infinite, force-damage at range via magic missiles is another "urgh"-moment that made me shiver. The diminished version definitely needs a weaker damage-type, an attack roll- whatever.
Don't get me wrong - this is an interesting pdf, it really is. The base system is great and Timothy Wallace is a talented designer, but I feel it falls flat on its face with the utter cluster-f*** that the vastly increased cantrip-array represents. Indeed, the problem is not only the added flexibility, it is the sheer balancing of the cantrips versus existing ones, with the diminished spells continuously outperforming the original cantrips. Furthermore, the diminished spells among themselves cannot always be considered balanced. I really enjoyed the first installment in the series and to see this one come apart to this extent has been pretty jarring. I cannot recommend this installment of the series, as much as I enjoy quite a few design-decisions herein - the balance-concerns are simply too pronounced, even for high fantasy gaming. That being said, at the same time, this does not deserve the slap in the face that is a 1-star rating -there are good ideas to be scavenged herein. Hence, my final verdict will clock in at 2 stars, while I hope for a return to form with the next installments.
I don´t think the diminished spells are balanced to be cast at will as 0 level spells. I would sugest that diminished 0 lv spells are spended as if they were regular spells.
