Liber Influxus Communis

So this book introduces 14 new classes. There are other things but I'll spend a lot of time on the classes.

Battle Lord
Battle Lord makes as much sense as anything else. Of course it has the same problem that I generally find in classes like Cavalier and other support classes in that how broken it is depends on how many martials are in the same area. This will make a nightmare of an NPC but relatively niche for PCs. I like the class

Conduit
The Conduit is much more interesting than I thought it would be. I thought it would be weird and cumbersome but mechanically this is pretty nice. I'm guessing he can absorb AOE spells if he's in the target zone? My only real problem is that my games will have veils, spheres, powers and other non-spell magics so this guy may have limited use in the future. I've heard promises of a patch that works in other magic systems so there's that to look forward to although if you're in a low magic situation the problem still persists. Also there's kind of an 'Uphill battle to awesome' situation here where fighting casters buffs you which is a dangerous thing to do. Its not really bad as it has plenty of workarounds but requires a clever player to make the most of the dynamic. I like the class.

Demiurge
I was skeptical about the Demiurge as soon as I saw that there is a complexity disclaimer, and low and behold I still don't quite understand how the class works. So it gets 'Enlightenments' which are pretty much Demiurge domains but where it gets tricky is the Fascimiles and everything involved with them. They are obviously 'creatures of law' considering that their abilities read like a contract: "rhetoric always involves two facsimiles, one that is designated as the “argument” facsimile, and the other as the “arguer” facsimile.". Oh god there has to be a way to explain what these things are doing without a huge use of philosophy book sub-terms. I can barely read the class and even then I'm forced to track a large number (quintessense) and my mental constructs need directions measured in commands that I don't feel are well defined. At the moment this class is banned from my games until it's rewritten to be simpler or I figure out how it actually works. Its just a philospher with summoned thought constructs. I really don't like the class

Medium
With Paizo's upcoming Medium, Radiance house's Occultist and Thunderscape's Thaumaturge I was not looking forward to looking at this class. Its basically a class that has the spirit of another character that it can gain abilities from.It has a place despite the Occultist medium and Thaumaturge existing so I don't dislike it as much as I used to. Its fun, somewhat unique and allows for an interesting playstyle. I'm okay with the class.

Metamorph
The Metamorph is something that I felt I'd seen before (LJP's The Host) but its a bit more refined and diverse. It feels like an eidolon and a sorcerer had a baby, with a bloodline-like selection that gains powers and access to evolutions. If you want to 'play the monster' like a sorcerer without the baggage of being a full arcane caster then this is the class for you. I love the Genesis concept allowing a lot of different flavors to fall into the class. I really like the class.

Mnemonic
The concept of blue mages in Pathfinder is a hard road to travel becaust there are so many kinds of abilities in the game (more if third parties are involved) that scale differently it's hard to determine how such a thing would actually work. The Mnemonic works well enough for that I guess. Its way less book keeping than other classes I've seen that try the concept out (Rite Publishing's Taskshaper) and for that it gets five stars. I like that it doesn't even try for spells. Overall I like the class.

Momenta
Sort of the Wendy and Marvin of classes. I don't mind support classes. I've had players be each other's butler and this class fills that role. I do have a complaint that it gets points at the start of combat rather than regaining its pool after a minute of rest. I just hate abilities that call out whether it works in or out of combat but that's kind of a minor complaint since the Inquisitor already prompted me to have to define the beginning and end of combat so no harm done. I really enjoy the idea of using the Momenta to make a 'Princess' or aristcrat character. This class is a good way to go about the concept which is great because most other solutions I've seen involve class-based gold acquisition (I hate class-entitled treasure) or some sort of social subsystem. I really like the class.

Mystic
When the Kineticist came out for the Occult Adventures playtest it became the playtest's darling for being the most mechanically fascinating and weakest class in the playtest. The Mystic is less mechanically interesting but definitely stronger and more interesting in other ways. Smart move in making it off of the Monk's chassis, as it adds some flavor and doesn't pigeonhole the class into being 'the blaster'. The class itself is surprisingly rich by comparison too. Two mystics of the same element can look drastically different. I really like the class.

Pauper
The whole despair/hope mechanic irks me for being fueled by something so abstract and environment dependent. I feel like its an argument waiting to happen. Other than that its an okay class despite being the most wimpy flavor-wise. Think of being the brunette girl from Yugioh and that's the class here. I'm not sure if I like the class, I feel like it could have been absorbed by the Momenta.

Survivor
The survivor is probably the most boring and best functioning class here. I really like it. Its basically a spell-less ranger that's not a racist serial killer or too bogged down by the whole nature them. I feel like chest hair should have been a class feature. I like the class.

Synergist
There are a lot of support classes in this product. I think designating people as your cast feels kind of useless. It feels like just more language. I like the class but it doesn't excite me as much as some of the others.

Umbra
Okay so this has two pools of points that have a third term for what they are collectively? I know its somewhat nessesary but couldn't things be built so that it doesn't need a laundry list of extra language? I feel like I have ADD with some of these classes, add to that some of the classes have relatively esoteric terms. That said this doesn't apply to this class that much, its just not complicated like the and doesn't require too much bookkeeping. Its kind of like an incarnum kineticist, getting power to invest in ties to different inner planes. I like the class.

Warloghe
Warlogue is the spooky class. Basically someone taited so attracts and can bind spirits in a minor way to pretty much become a walking haunted house. I like the class a lot.

Warsmith
This class is boring. Its practically a Magus' Arcane pool attached to a crafter with some sunder sneak attack ability. I love it! Its kind of the artificer I've always wanted without weird mechanics or some kind of spell-like technology. Just a guy that can make stuff and break stuff really really well. But seriously this class deserves way more support.

Chapters 2 and 3 are pretty basic. Just some things to support the classes. Nothing terribly fascinating or gamechanging. Then there are new haunts and hazards which are nice.

Overall I have problems with the Conduit and Demiurge but a lot of these classes add to niches unexplored or refined rare niches that other products have only graced. Even the ones I complained about brings something new to the table and the two most boring classes are some of my favorites. There's enough holes filled that I want to call this a must-have but I feel like its not for everyone as it hits a few pet peeves I have on class design. If the problems above aren't your kind of problems this is a five star, but I'm giving it four stars.
