It is possible we are in agreement.<snip>
What a miniclass class must avoid is weird requirements (like proficiency in a specific skill, or so on).
Keep the miniclass a normal class, and balance it like a normal class, and it works fine.
It looks like we...almost agree. It depends on what you consider "weird" requirements. Going back to my silver pyromancer example above: this is a PrC specifically for arcane (and only arcane, not divine and not warlock) casters who are vetted by, and then inducted into, a religious institution that teaches them special applications of their arcane casting. Given the explicit vetting process, I don't consider "you have to be trained in Religion" to be a weird requirement
in this context. From both personal experience and knowing several others who have initiated into lay-faithful organizations, I would in fact think it weird to
not have such a requirement for this specific example. Likewise, a prestige class that deepened the options available for wild shape might require proficiency in Nature--you need that baseline.
However, I am absolutely in agreement that naughty word things like requiring Channel Divinity
and Bardic Inspiration or Superiority Dice
and Smite Evil (etc.) would be completely inappropriate. Every prestige class should be viable for most characters with,
at most, picking up a trained skill at the start, or taking a feat at level 4 in order to qualify (Skilled, specifically). You should never need careful build planning, because that is bad design and we have the entire crumbling edifice of 3rd edition to demonstrate it.
The reason I say "most" characters is I do think some PrCs warrant the ability to cast spells. That does, technically, cut off a portion of classes...but not a particularly big portion, depending on the details. (Heck, a five-level PrC that requires 3rd level spells would still fit into an arcane trickster or eldritch knight, to say nothing of Paladins and Rangers.)
Instead of the term ‘prestige’, it might be more useful to link it by tier.
• Levels 1-4: Basic class.
• Levels 5-8: Expert class.
• Levels 9-12: Master class.
• Levels 13-16: Leader class.
• Levels 17-20: Legend class.
(Levels 21+: Epic class).
Hypothetically, for the sake of an example. A Vampire miniclass might only have levels for the Expert tier and the Master tier. Any basic vampires might be ineffectual drones, perhaps even perpetually Charmed, while only higher level vampires become autonomous and powerful. The expert miniclass would supply the more potent Vampire abilities, while the master miniclass would supply the high-level Dracula-esque abilities.
The Shadowdancer might be a basic miniclass, with the essentials of shadow magic that any character can take at low levels.
Note, the master tier is when the character becomes the head of some institution: a guild, wizard tower, military fortress, or so on. The leader tier is when they become movers-and-shakers within national politics. The legend tier is when they impact the affairs of the world or plane.
It makes sense if certain miniclasses are pertinent to these specific magnitudes of political influence.
All of this sounds perfectly cromulent to me. A silver pyromancer, by being someone who
started off with arcane spellcasting and then got some religious training atop it, would make sense as an expert (leaning into master) class: by the time you finish it, you very much
are an expert in the field of fighting evil outsiders and undead, and potentially have risen to a position of influence (dare I say
mastery) within the non-cleric church hierarchy.
I'd call them Prestige Themes
Ex: Prestige Theme: Vampire
Prerequisites: Being afflicted by the curse of vampirism, minimum level 5
1: Drain blood: As a bonus action deal 1d4+level extra piercing damage when attacking with Advantage, recuperate the same HP amount. once per short rest
2: Child of the Night: Regen 1 Hp/round when under 1/2 HP, lose it if in direct sunlight or hit by fire or radiant damage.
3: Forms of the Predator: Take the shape of a Direwolf or Swarm of Bats for 10 minutes, once per short rest.
4: Resilient Obfuscation: Double prof in stealth, can hide in dim light, resistance to all damage but fire and radiant when in complete darkness.
5: Undying Vitality: Requires 4 death save to kill.
Is this a feat chain, or a class? As a class this sounds alright, though I'd want some design passes (it feels a little weak, but definitely on-theme.) I am completely opposed to making any kind of "feat chain" that sucks up all your feat opportunities. That's an incredibly punitive cost, and would almost certainly never be worth it--we should be encouraging flavorful choices, not locking them behind a cost almost no one would willingly pay.
I came here to post exactly this, though I'm not sure how I'd implement it. In 4e it was a straight-up add-on, though I'm not sure how well that would fly in 5e
Making something that just sucks up all your ASIs seems an excessively punitive cost, given that "you might lose 1-2 ASIs" is seen as an appropriate balance point for getting to multiclass.
Essentially, what I'm thinking of is a 5-step Feat chain (all PCs get at least 5 ASI/Feat slots).
See above. The primary result of this would be that no one would take them unless they're okay with being dramatically weaker than everyone else, and that's Pretty Bad. Unless...I guess you could have the 5-step-feat-chain grant stat bonuses to the chain's core stat(s). But then you're looking at them really being "half-feats," and a chain full of half-feats is probably going to be extremely lackluster. This is the problem I kept running into while looking at homebrew silver pyro stuff. On the one hand, anything that sticks to the power curve
and exclusively uses feats either ends up bland, fails to capture the core concept, or both. Anything that breaks from the power curve in order to exclusively stick to feats
and retain flavor/core concept...well, it breaks from the power curve, being either weak enough that it feels like a punishment for doing something flavorful, or powerful enough that you'd be foolish not to pursue it even if it doesn't fit the character.
That's a big part of why I started thinking: is this the place for "whatever PrCs should have been"? (Because apparently the term 'prestige class' is so poisoned by its 3.5e version that it's become anathema, to invoke the name is to summon its awfulness.) The space of things that:
- several different classes (and perhaps all classes) should have access to
- are too strong to be squeezed into a single feat
- would force players to choose between effectiveness and flavor if it cost multiple feats
That space seems to have fertile ground, to me. Subclasses can't cover it, because subclasses are too specific. To make up a (likely faulty) example, consider something that anyone who can Extra Attack can learn to do. It would require subclasses for Fighter, Barbarian, Paladin, Monk, and Ranger--and it would fall down with the Valor Bard, because that's a
subclass feature. Or, instead of writing five different subclasses, you could write one (ahem) "expert class" that covers the relevant stuff. Plenty of things
shouldn't try to squeeze into this space. As a player or designer, one should usually first ask whether the other kinds of customization (feats, subclasses, a full class, a list of spells, etc.) are able to fill in the gaps.
