Geometric Binder

The Geometric Binder is a class I think has legs, and have not had the time to finish up. I’ll post the current draft here, and if/when finished I’ll do a version in The Showroom. Very open to feedback on this.

The goal of the Geometric Binder is to serve as a replacement to the 3.5 binder class, which was fine, and give something a little bit more thematic. This puts more focus on the binding portion of the class, and makes it less of a pick your set of SLAs.

The Class

I invoke the powers of the Wind and Corruption to bind thee, devil. Be bound and submit to my will.  

The Geometric Binder is the archetypal caster type focused on tapping into the dark power of devils. They have a selection of at will and per encounter abilities they can select and modify on a regular basis. Most abilities start as enhancements to the binder’s form, making them take on aspects of the evil entity, but eventually they learn to summon, control, and even lord over them. 

Hit Die: D8

Skills: 4+Int; appraise, bluff, concentration, craft, decipher script, forgery, gather info, intimidate, knowledge (all), profession, sense motive, speak language, spellcraft, use magic device.

Proficiencies: Simple weapons, light and medium armor, and shields. 

BAB: Medium

Saves: Good Fort and Will.

Binding: Binders can spend 5 minutes drawing a Sacred Shape on the ground, fully enclosing a Seal, and calling forth an avatar of a select entity. This entity emerges from the seal. At this point, the binder must pay the associated costs, and can then converse with the entity. The binder has one hour to choose whether or not they bind an entity, by stepping into the circle and absorbing its essence. A binder who chooses not to bind an entity can dismiss them as a swift action. Once bound, the entity remains so until the binder is slain, or chooses to release their hold. A binder knows the seal for one entity per level. A binder’s caster level for all class features is equal to their binder level. If they have an ability that requires a saving throw, the DC is 10+1/2 HD+Int Mod.

Sacred Shapes: When drawing a binding shape, you use one or more of the sacred shapes. You can use one sacred shape at 1st level, and an additional at level 4, and every 4 levels thereafter. You unlock abilities for each entity based on the shapes used to bind it. EX: When using a single circle to bind an entity, you gain the first circle power. If you use use two circles, you gain the first two circle powers. If you use a circle and a square, you gain the first circle and first square power. When binding, you always get an entities communal powers. 

Bound Knights: At first level, you have access to bind Knights. As you reach level 4, you can begin to learn how to bind Presidents, on to Marquis and so on. 

Communion – Augury: You can cast the augury spell as a spell like ability with a few exceptions. First, the casting time is 30 minutes. Second, the answer is provided by the bound entity. The entity is still bound to answer as per the spell, but if the spell fails, they are free to answer as they wish. This ability can be used at will. 

Summon Avatar: As a standard action, you can summon the avatar of your bound entity. This creature remains summoned for 1 round per binder level. You can summon an avatar once per hour. 

Communion – Commune: You can cast Commune as a spell like ability with the same restrictions as per Augury. 

Bind Avatar: You gain the services of a familiar with the following changes. 

  • Your familiar does not use your skill modifiers, but rather always its own. 
  • Your familiar changes form based on what you have bound. It always has the statistics of an avatar of your entity, with the familiar modifiers applied afterwards. 
  • Your familiar’s intelligence score changes with its current form, not the normal familiar progression.
  • If your familiar is slain, you gain a new one next during the next binding ritual. 
  • If your familiar changes form, it heals as though from a nights rest, but otherwise damage carries over to its new form. 

Communion – Legend Lore: You can cast Legend Lore as a spell like ability with the same restrictions as per Augury. 

Lesser Retainer: You can summon 2d6 imps as a standard action with a 75% chance of success. These imps last for 24 hours or until slain. 

Demand Rank: By 15th level, while not a Devil in name, you are known in infernal circles. As such, you can reasonably demand a noble rank. Along with your rank, a fairly intangible benefit, you gain the common traits shared among all devils. Your type remains the same.

  • Immunity to fire and poison.
  • Resistance to acid 10 and cold 10.
  • See in Darkness (Su): You can see perfectly in darkness of any kind, even that created by a deeper darkness spell.
  • Telepathy.

Demand Title: As you grow in prestige, you can demand an infernal Title. While infernal Rank means the nobility will talk to you, a title means you have actual governing duties, and can apply punitive measures against those who choose to insult you. You are granted divine governing control of an area of Hell by Asmodaeus himself. You can assume to be collecting enough taxes to sustain a gaudy Hell Castle (use Huge Castle Stats), and are given divine authority to govern a 6 mile radius per 5HD. This territory generally contains a Large City and a small town per 5HD you have beyond 5. Your territory has a lawful evil power center, and NPCs as appropriate for one of its size. Your territory is on a Layer as deemed appropriate by your GM. 

Greater Retainer: You can summon 2d4 Bone Devils as a standard action with a 75% chance of success. These devils last for 24 hours or until slain. 

Final Demand: You are treated as a lesser deity within your domain, and as such gain access to the divinely morphic properties of the infernal planes, while within your realm. If your realm expands through conquest, your reach expands along with it.


What do the entities who get bound think?

Broadly speaking, none of the bound beings enjoy being bound. Think of it as a perpetual tug at the back of your consciousness. That said, binders who frequently bind the same being may develop a certain rapport or understanding. Another important note to keep in mind is that many, or most, of these entities are very persuasive and have goals of their own. If the right bargain is struck a binder may be able to get a willing participant. The DC for such a check is the same as it would require to bring a hostile creature to friendly using whatever diplomacy rules your group is using. While in communication with the binder, an entity cannot use SLAs or activate abilities against them through any means. They are able to send servants or ambassadors in order to persuade the binder against continued binding, but cannot directly take action against the binder. (GM Guidance: these servants should not be of a higher EL than the players should normally expect to face in the course of normal adventuring)

Can I communicate to something I’ve bound

Yes. This can be done in a few ways. First, through the use of your communion ability. Secondly, you and the bound entity share a telepathic bond. While, the entity is under no compulsion to converse with you in a helpful manner, or at all, they might. 

If I bind something, can others bind the same entity?

Yes. All of the devils listed are powerful entities on their own. Binding it only uses a fraction of their power. They aren’t super excited to share that fraction, but it doesn’t stop them from being bound by others. 

How does this square up with a WoTC cosmology?

It doesn’t particularly well. The bindings are from the Lesser Key of Solomon. So… Christianity kind of… or “The Occult” broadly? Anyway, you can swap some names to a WoTC setting if you want, or sub in Golarion if you prefer. You’ll have to do setting work, but most GMs have to do that anyway. The Demand’s may require that you use the demographic stats and planar traits from the DMG which may not translate to other games well. 

This is the coolest. Do you have expansions planned?

Thanks Hypothetical Question Asker. This seems like it wouldn’t be a lot of effort to have a variant with demons, angels, or fey. Other types seem like you could technically, but like you’d lose some of the flavor. A giant binder seems kind of dumb.
