There are a lot of attempts in Pathfinder, first and third party alike, to adapt extremely specific concepts from other media to Pathfinder. Most are clumsy, or at least obvious references. This takes FFXIV's Reaper job and its flavor in several directions that can fit seamlessly into the Spheres system and a typical PF game without feeling forced (or you can just drop a Reaper into your game if that's what your table likes!) It's a lot of fun mechanically too, probably my favorite Striker archetype :-)

3 Archetypes for classes (I guess technically 4,) and the cornerstone of the book, Conjuration Companion Archetype the Avatar.

The Avatar is a neat concept where it's kind of like a phantom from Spiritualist in which it can possess just kind of live inside the wielder, but rather than being able to be summoned at any point and act as a full on Eidolon like most conjuration companions of the Phantom, it instead only really gets to do stuff through class features.

Both the Void Conduit and Void Dancer do stuff that I find to be pretty awesome. Without deep diving too hard into the archetypes I do love that they themselves get the ability to do stuff on their, the caster's turn, to give an action or ability or whatever to their companion, the Avatar, to do in their stead. Obviously because the Avatar is never summoned this is a necessity but I am a huge fan of being able to command summons so that as a summoner I can feel like my turn is still related to the Conjuration Companion and I'm not just off in some completely different sphere doing my own thing while my companion does another.

Void Rusher is something I absolutely adore. In addition to just loving the reference it is based on, I love the thing that Prodigy has in it where it can build up Links in a Sequence and do a cool Finisher. Void Rusher allows the Striker to do something much similar, in having a resource build up and then allowing you to ahem, engage in hype beast mode. Technically speaking Striker could already do this by spending all of its tension in one round and giving itself a +whatever to hit and damage, but the way its done in Void Rusher is way cooler. Also it can use weapons, that's dope.

Overall, love the book, the archetypes.

I like the idea of a martial summoner, and this product definitely delivers that. It's the closest that Spheres environment comes to the Paizo Synthesist archetype, by letting a powerful companion possess you and take actions on your behalf.

This is very interesting and unique content. The Avatar archetype for Summons is not represented elsewhere, at least not as well.

Absolutely stunning book. Great to work with without upending the game to make them fit for the environment they were designed for. Plus they're extra fun if you're a fan of final fantasy, jojo's bizarre adventure or just being a cool monster.

Definitely a top tier product, as has become the standard for DRS. I couldn't imagine what a Conjuration focused Prodigy or Striker archetype would look like but they turned out amazing. The Voidrusher in particular is among my favorite archetypes in all of Spheres. The contents of this book provide a thematically cohesive bundle of archetypes with a level of mechanical clarity and balance that Rex so consistently provides for all to enjoy.
