This is a terrible product. The Psion archetype that opens the book does not gain any new features until 8th level. The new features are bland and mostly pointless, which is true for all the archetypes in this book.

Add to that the options that just do not function and the terrible rating and rampant errors and flaws, and this is an utter waste of money even at the low price it is currently sold at.

Mind over Matter: Book 1 Scion and SoulKnife, is a supplement specifically for Dreamscarred Press’s “ Psionics Unleashed”. Both books are compatible with Pathfinder. The PDF sells for around $5 and is 20 pages, 4 being non content. This pdf is stocked full of some really great ideas and includes a lot of crunch for the Psion and Soulknife. First thing I noticed was that instead of Prestige Class they used the term “Archetype” and instead of gaining individual hit dice, base attack bonuses etc like Prestige Classes, they just gain abilities at certain levels. I do own the Psionics Unleashed and the core Pathfinder books and have never ran across the term. Which leads me to other question like “if you take a Archetype do you just add on the ability at the right level?” The pdf gives no explanation, assuming you know about it already. So unless I’m forgetting something..

Beyond that though the ideas are really great. Introduced here, for the Psion are the archetypes of Locus (being able to be in more than one place at a time) and Mindreaver(able to hide in the Psyches of the victim) For the Soulknife we get a somewhat forgettable “Attenuator” a sort of monk like guy and the Magpie, a thief-like character,that can steal things right out of the hands of people including weapons. In my opinion this archetype is somewhat over powering not so much on it’s own, but when combine with everything else. Even the gaining and losing of a skill relfects this when you gain slight of hand and lose swim.

The pdf also have a few new feats and even two new afflictions, Delirium and Psychalgia. All very good.

The pdf has a Mythic Class the Medium. Playing this one requires that you have another pdf called “Mythic Adventures”. Making the total books you need to use this pdf to at least three ( A core rules book, Psionics Unleashed and Mythic Adventures).

So overall my thoughts. For the price you get a lot of really great ideas with sound mechanics. Needing at least three other books to use it all not so good. And again, unless I’m forgetting the concepts of Archetypes from another book, there needs to be more explanation on what they are.

this book gives some interesting insight and options for different Psion paths. a few are more RP useful where others can accent how a player resolves their combat.

Mind over Matter: Psion and Soulknife adds a novel amount of depth to the already enigmatic psychic classes.

For the Psion, the new archetypes add a darker, more violent way to engage foes. The Mindreaver attacks the mind while the Locus attacks from impossible angles, lending to the inherently mysterious nature of this class. The Soulknife gains the Attenuator and Manic Magpie archetypes. The former turning the soulknife in the classic weakness-seeking, body-flinging psychic. The Manic Magpie is fantastic for psionic-heavy campaigns, but still shines in a world where these sort of powers are less prevalent. It lends the soulknife of steal a variety of enemy tools to use for their own.

Combined with the new feats and powers available to both classes and the corresponding archetypes, you can go from a simple psion to a shadow lurking, mind-bending battlefield controller or be - literally - everywhere at once.

The addition of Mythic paths and powers helps to being the psionic classes in line with the core classes in terms of powers, plus they are unique and not simply rehashes of magic abilities are psychic powers tend to be.

Overall, if you're looking for unique and powerful options for these classes, or a way to incorporate a psychic class into a mythic campaign, this is a fantastic addition. If you're the only psionic character, or you simply want a unique boss, the core psionic rules will work just fine.
