Question I’ve been mulling over: is a Savant 1/3 caster a bad idea? Specifically, I’ve been taking a look at my Arcana-focused Savant idea and wondering whether it should have some spellcasting.
I would say it's fine. Fighters and rogues are traditionally non-magical, but they had 1/3-casters in o5e. But...
If it does have spellcasting, my notion is that such Savants usually consider themselves Wizards, but spend more time with each spell and have a narrower focus, allowing them to rapidly create rare spells, making them mildly Sorcerer-like in the process. (Adjacent question: would such Savants have spellbooks or be known casters?)
I wouldn't focus on rare spells, since that's still a downtime activity. It could be a ribbon ability, but not a main draw of the archetype. What I would do is actually give them some sorcerer metamagics. They learn a few spells (far less than a wizard would), and have to prepare their spells via books, like wizards do, and can only learn spells from the wizard's spell list (such a restriction, I know), but their intense focus gives them the ability to modify those spells in a sorcerer-like way.
Another possibility is that they have the ability to tweak
other people's spells by using metamagic. For instance, they see someone cast
fireball, they could spend a point or two to use the Subdual metamagic so that the targets aren't killed but dropped to 0 hp, or more points to create a "Lessened" spell that acts like the reverse of a Heightened spell--a target has advantage on the save, not disad. (Or vice versa--they could help out an ally's casting this way) This could be limited to spells that are on the wizard spell list, to represent only their field of knowledge.
(Of course, now that I think about it, this function might work well as a Martial archetype instead.)
If it shouldn’t, then the design focuses on someone who knows as much as a wizard does but keeps a distance from spellcasting, perhaps because they’re magically impotent, a fanatical mage hunter with moral reservations about magic, or just doesn’t like getting their hands dirty.
The problem is that if Savants are going to be a 1/3 caster, they’re going to be INT-based, which is already their primary ability score. In addition, they would have to get spellcasting at level 1 or 2, as they have no third-level archetype feature. I’m worried that such an archetype would be too strong, and potentially even introduce a dangerous multiclass dip for wizards.
Thoughts?
In
this case, you could say that instead of spell slots, they get spell points like warlocks. This would only be a problem with multiclassing into an Int-based warlock, but you could also say that the points don't stack. Savant spell points (call them something else) only work with savant spells.)
