Tome of Battle already includes two great feats for non-martial adepts, Martial Study and Martial Stance. For a character made with the Fluidity Project, these feats are a boon, but the distinct lack of a high initiator level or a recovery mechanic means that such a character cannot make full use of the maneuvers presented in Tome of Battle. The below feat is designed to alleviate this problem.

PRACTITIONER OF THE SUBLIME WAY
Prerequisites: Base attack bonus +3, Martial Study (see ToB), Martial Lore Rank: Trained (see ToB)
Benefit: Your initiator level is equal to your base attack bonus. You can ready a number of maneuvers equal to 1/3 of your total hit dice (minimum of one). You can recover your expended maneuvers by spending a full round action to do so.
Normal: A character’s initiator level is equal to half his total hit dice.

The Tome of Magic also contains feats that are a boon to characters that wish to dabble in either soul binding or truespeaking. The below feat, True Soul Binding, may be a bit powerful. If you find it to be so, requiring a player to purchase the Bind Vestige feat for each vestige they wish to have access to would be a good fix.

TRUE SOUL BINDING
Prerequisites: Bind Vestige (see ToM), Improved Bind Vestige (see ToM), Practiced Binder (see ToM)
Benefit: You gain the soul binding special ability. For the purposes of binding vestiges, you are treated as a Binder with a level equal to your hit dice (see ToM). You gain no other features of the Binder class, this feat only allows you to bind more powerful vestiges, benefit from all vestige abilities when you bind a vestige and purchase feats which have Soul Binding as a prerequisite.

Some more homebrew vestiges can be found here. There are also several official sources of vestiges:
Dragon Magic (Ashardolon)
Dragon Magazine #341 (Primus and Kas)
Design and Development article (Vanus)
Mind’s Eye article (Abysm, Arete, The Triad)
Cityscape Web Enhancement (Astaroth, Deshartis)
Class Chronicles: Binders (Zceryll)
Dungeon Magazine #148 (Ahazu)
Dragon Magazine #357 (Astaroth, Ansitif, Cabiri)

The utterance feats (Minor Utterance of the Evolving Mind, Utterance of the Evolving Mind, Utterance of the Crafted Tool and Utterance of the Perfected Map) should suit a character built with the Fluidity Project if the skill prerequisites are converted. However, if a player wishes to speak utterances higher than 1st, allowing Utterance of the Evolving Mind, Utterance of the Crafted Tool and Utterance of the Perfected Map to grant access to higher level utterances shouldn’t be a game breaking change.

The other option for a DM who wants to delay a character’s access to higher level utterances, but who wishes to take full advantage of truespeaking is to keep the existing feats that allow a character to select 1st level utterances in each lexicon. And to use the three feats below.

UTTERANCE OF THE EVOLVING MIND
Prerequisite:
Truespeak Rank: Trained, Skill level 9, Minor Utterance of the Evolving Mind, know at least three utterances
Benefit: You learn one utterance from the Lexicon of the Evolving mind.
Special: You can purchase this feat more than once.

UTTERANCE OF THE CRAFTED TOOL
Prerequisite: Truespeak Rank: Skilled, Skill level 12, Minor Utterance of the Crafted Tool, know at least four utterances
Benefit: You learn one utterance from the Lexicon of the Crafted Tool.
Special: You can purchase this feat more than once.

UTTERANCE OF THE PERFECTED MAP
Prerequisite: Truespeak Rank: Mastered, Skill level 15, Minor Utterance of the Perfected Map, know at least five utterances
Benefit: You learn one utterance from the Lexicon of the Perfected Map.
Special: You can purchase this feat more than once.

Unfortunately, as cool and flavorful as Shadow Magic is, there are no plans currently in the works to offer a conversion for it. The core magic system in Fluidity Project could be retrofitted to provide an avenue for those players who wished to pursue Shadow Magic. But, right now, all the focus for the project is directed towards finishing Elementalism and the third magic system — Ethercraft.
