||This pdf is 45 pages long, 1 page front cover, 1 page editorial, 1 page SRD, leaving 42 pages of content - so far the best bang-for-buck ratio in the series, so let's check this out!
After the by now obligatory introduction-page, we are introduced to the new Aegis-base-class. The Aegis gets d10, 4+Int skills per level, proficiency with simple and martial weapons, light armor and shields, up to 70 PSP, full BAB, good fort-and will-saves and up to 26 customization points. What is the Aegis? Essentially, the Aegis is a tank-class that is similar to the soulknife in that it takes psionic powers to construct something, in the Aegis' case, a custom suit of armor. The astral suit can be customized via a vast variety of customization options that include extra arms, wings, adhesive feet and similar goodies. Sounds familiar? Yeah, the closest analogy I can come up with is being a fighter who pilots his own, mindless eidolon, but without needing to play two characters. The Aegis' suit also grants improving DR, can be customized faster at higher levels etc. Sounds like a cool, balanced class? Yep, it is. Nothing to complain about. Great customization-options, versatility, iconic imagery, cool artwork.
Two psionic disciplines are introduced as per the other pdfs - this time, though, they are slightly more complex: The Maestro is an expert in astral constructs and can construct astral swarms instead (CR 7, statblock provided). The erudite-discipline offers us the options to manifest a minor amount of powers sans paying the power point cost when being focused.
The soulknife gets the gifted blade archetype, who can also manifest a limited amount of powers, 7 total of up to 4th level (this time, the power list is included in the pdf). The pdf also includes 3 new blade skills. This installment of PE also includes 28 new feats for your perusal that range from improved advanced constructs and include a massive slew of metapsionic feats that include dealing subdual damage and similar effects. From elemental effects to the ability to exclude allies from your area-effect powers, the selection is rather useful for aspiring manifesters, especially due to the inclusion of feats that let you dip into psionic powers without belonging to the psionic classes.
The new powers include the now (with the advent of rogue talents) unfortunately-named talents, which essentially are a psion's cantrips and include information on how to implement them in your game for the different classes. More interesting, knowing certain 1st level powers grant access to certain talents - a smart method of rewarding smart choices.23 powers are included, some of which overlap or are talent-versions of 1st-level powers. The classes from PU get a very detailed treatment in this installment - alternate racial traits and favored class options are included for them and favored class options for the core-races are part of the deal as well. That's not where the trait-extravaganza ends, though - psionic traits for psionically active characters and non-psions are introduced as well as psionic traits specifically designed for the PU-races. Commendable and always cool to see extensive support for new content.
In contrast to the other PE-releases so far, this one actually contains two new PrCs instead of one. The first one is the Metaforge (d10, 4+Int skills per level, full manifester progression, full BAB, medium will-save), a variant that enables access to an Aegis' suit and a soulknife - very cool psionic knight! The second is the Psicrystal Imprinter (d6, 2+Int skills per level, bad BAB, medium will-save, 9 levels of manifester-progression) on the other hand is a specialist who manages to imprint and store powers in his psicrystal. Interesting PrC with regards to crunch, but I'm a bit torn about the classes iconicity. Apart from that, nothing to complain about with these PrCs.
The pdf closes by providing 5 new psionic items, including boots that grant/improve the nomad's step ability. Neat items, nothing to complain here either.
Editing and formatting are top-notch this time around, I didn't notice any glitches. Layout adheres to the 2-column standard and the artwork is mostly b/w and again, inconsistent in style - the aegis is by far the best piece of artwork herein. The pdf is fully bookmarked. Of all the pdfs from the PE-line, this one not only provides the best bang-for-buck-ratio, but also includes the best base-class in terms of design and iconicity. The Aegis is iconic and, while not subtle, very cool and something that has not been done before. The rest of the content, including the archetype, is up to the standard and no botches in design would detract from the content. Add to that the talents, traits and the very cool Metaforge-PrC and, apart from the inconsistent art-styles, I have nothing to truly complain about. Thus, I'll settle for a final verdict of 5 stars - well done.
[5 of 5 Stars!]
