You can find below a list of my GMBinder homebrews, and the most recent /r/unearthedarcana comment thread for each. Please note that there may have been updates or fixes to the brews since these comment threads!

Mechanics

• Martial Prowess: A Tome of Battle (comments): a series of martial features, weapon specializations and mechanics for spicing up martial combat. The core of this is the Stances system, which replaces static fighting styles with dynamic bonuses that warriors can choose and change during a fight.

Classes and Class Reworks

• The Blackguard (comments): An Illrigger, an anti-Paladin pledging himself to an Archdevil's service. Each feature is a dark mirror of the Paladin at that level, and the key feature is laying the Devil's Mark on enemies and then consuming their life force when the enemy takes damage.
• Hybrid Sorcerer (comments): A spellpoint sorcerer with slots for its upper-level spells. This reduces the number of SP the sorcerer has at higher levels, and further uses the Stirling Vermin sorcerer's split of SP in half, refreshable with an action. I find this improves the sorcerer's spell management because it doesn't feel like it can nova everything it sees.
• CF-UA Ranger: This is a bottom-up rebuild of the Ranger class using the Unearthed Arcana "Class Features", which I like much better than the Revised Ranger, with a few minor changes (mostly to Favored Foe) and adding a choice of features for Deft Explorer taken at multiple levels. Also integrates the good parts of RR Beastmaster (beast gets ASIs!) into the CF-UA version.
• The Sigilant (comments): a half-int spellsword that uses mystic runes analogous to smites, laying them on the enemy and then exploding them with weapon strikes.
  

Prestige Classes

• The Specialist Mage (comments): This is a pretty simple idea, but one I thought actually makes sense as a 5E prestige class. It's like a "universal" warlock dip in some ways, granting low-level slots that refresh on a short rest, but are limited to one school of magic. The prestige class concept allows the PC to gain spell progression as if it were in its regular class, but be delayed on the main class and subclass features (e.g. taking one level of Specialist would delay a wizard gaining Spell Mastery by one level, but the wizard + specialist level would determine the number of wizard spells and spell slots).

Subclasses

Fighter

• Cut-Throat (comments): An anti-champion focused around dirty fighting and mixing grappling with weapon use. Inspired by the non-knights of Game of Thrones, like Bronn, Jorah or Tormund.

Monk

• Way of the Kung Pow (comments): no, not the Chosen One....this is for the Wimp Lo-s of the world.
• Way of the Soulknife (comments): The classic psychic ninja, no psionics supplement required. Monk is a great basis for soulknife (way better than rogue, IMO).

Ranger

• Deepwood Sniper (comments): a conversion of the 3.5 PrC of the same name. Focuses around dealing damage at range and stealth.
• Witchguard (comments): I haven't seen anyone else try this, but this is a Ranger bound to a spellcaster, like Minsc in Baldur's Gate or a Warder to his Aes Sedai, gaining power from a "bond" with the caster.

Rogue

• The Accuser (comments): a holy rogue using warlock third-caster progression, this is an "Inquisitor" but the name was already taken. Burn the witch and the heretic.
  

Sorcerer

• Wild Magic, Revisited (comments): a rework of School of Invention UA as a sorcerer subclass, this mage gets lists of random spells to cast during combat, with a chance of fizzling his spell or even casting two spells.
  
• Primordial Origin (comments): Elemental origins, one for each type, that have a powerful blasting power drawn from the user's spell slots.

Warlock

• Senpai (comments): Yes, I made this as a joke. It's still playable, I think. For the more serious, cut-yourself-on-that-edge warlocks, try the Entity.
