So, I’ve been hard at work on the Binder, but haven’t posted here about it.
Here’s an updoot.
The class is still d6 HD, but now casts with Int, and has become even more of a ritualist.
Level 1, you get your Binding Seal (subclass), ritual casting with a Wizard/tomelock style book called a Goetic Key, and 1 Vestige of Power. Part of the ritual casting feature is that your rituals use three ritual tools, those being a musical instrument, a bladed weapon, and a receptacle of liquid, ie a Bell, Blade, and Bowl.
Level 2, you get Pact Magic, with 2 spells slots, and you prepare your spells and can learn new ones in the same way as with your ritual spells, and another Vestige. You can use the above ritual tools as Spellcasting focus for your spells.
Level 3, you get your first Vessel, which is one of three ritual tools. Your Vessel is a magic item that you can summon to hand at will, can be replaced as a 1-hour ritual, etc.
- The Vessel of The Bell, gives you Int to concentration on conjuration spells and on Spellcasting ability checks made as part of casting a spell, such as that of Counterspell or Dispel magic.
- The Vessel of The Blade, gives you an extra cantrip that requires an attack against a single creature, and you can cast it as a melee spell attack that also counts as a melee weapon attack, as an action. The wording is being tuned to make it do what I want, but the idea is you cast chill touch with you dagger or glaive or scythe and it has the reach of your weapon, including any thrown range, and you can use it any time you could make a melee weapon attack, and it works with smite spells and the like.
- Vessel of The Bowl, gives you an extra spell slot
Each vessel also allows you to learn a short list of spells, and has Vestiges that require a given Vessel. You can choose a second vessel at 9th level, and a third at 13th, eventually mastering all three ritual tools.
As you level you gain Vestiges at the same rate as warlock invocations, except at level 9, where you get a second vessel instead, and possible at a couple other points where I’ll add in some advanced ritual magic.
At levels 5, 11, 15 and 17, you gain Seals of The Greater Vestige. These “replace” the warlocks mystic arcanum, and are greater summoning abilities that you can use once per short rest. You gain a Seal known, and can only ever use a given one 1/day, but you can gain more seals known and basically prepare them like a spell.
Level 18 gives a base class capstone called something like Seal of The Final Gate or something, and level 20 is your final subclass ability.
Vestiges: an example generic vestige is the Reigns of The Erlking, which grants you the ability to speak to and understand predatory beasts, and grants proficiency in Survival and Animal Handling.
Others might grant the ability to cast a spell at-Will or as a ritual, steal ideas from warlock invocations, or grant abilities normally reserved for monsters. I’d like to include stuff that is a “ritual you can perform as part of a short or long rest” as well. Still others might increase the power of common ritual spells, like doubling the strength and duration time of Unseen Servant and allowing you to burn a spell slot to give it the ability to attack, with numbers based on spell level, or cause Alarm to force a save vs Stunned on intruders.
The second main set of Vestiges are Vestiges of The 9 Circles, which give you access to higher level spells. Eg, Vestige of the 6th Circle lets you learn 1 6th level spell, and allow you to cast a 6th level spell 1/day. You can learn more 6th level spells by adding them to your Key, but you can prepare 1 6th level spells and cast it once per long rest.
The last variety of Vestige or vessel vestiges, which require mastery of a given vessel.
A blade Vessel might boost your melee prowess with access to spells known you couldn’t otherwise get, and/or some other buff, flavored so it’s a significant magic item.
