Spells as encumbrance

What if spells took up inventory space?

Spells must be imbued into appropriate material. Each spell has an associated "typical material".
Higher level spells require bigger or heavier materials.
A magic-user preparing spells somewhere civilized can procure materials at no cost.
When preparing spells, the magic-user must imbue the spell's material with the spell.
The material must then be brought out to cast the spell.

Other than that, no changes to the magic system.

Example: Welby the Wizard (level 1 MU) is in town, preparing for adventure.
He decides he wishes to prepare Light, which he knows and has a spell slot for.
Light requires a bundle of incense (about 1 kg) which he procures, imbues, and puts into his inventory.
In the wilderness, Welby carries the bundle of incense around. When he reaches the dungeon, he takes it out to cast the spell, rendering the incense inert.

Potential advantages :
1) I feel like it'd be really nice to have all of a character's options in the same list. Rather than flipping between a spell page and an inventory page, Welby knows he has "Light-spell Incense" written down along with, "vial of glowing poison-fungus juice".
Encouraging the use of spells for "item problems" and items for "spell problems" sounds like a good idea to me.

2) It'd also make spell-users more burdened than other classes, which I like.
A high level MU or Cleric could have an apprentice tasked with carrying all those imbued materials.

3) Flavor. I don't think I need to elaborate why it'd be cool to require incense, odd ingredients and the likes for a spell to take effect. Uh... I don't think I'd require guano for Fireball though.

4) Balancing factor. If you think Charm Person is too good and needs to be toned down, but don't want to mess with the numbers, then making its ingredient take up five times as much space as the usual spell could be an answer. If you think Ventriloquism just isn't appealing, make it use lightweight cloth in the shape of a sock puppet.

Hey wait, isn't this exactly like that old ugly concept of "spell materials"?

Hopefully not! Here are the main differences in the way I'd handle it:
1) No fetch quests. If you're in civilization, you can get the item. If you're not, you can't. No having the game devolve into guano gathering. (In my house rules at least it doesn't matter whether you can grab the material in the wilderness, anyway, because you need to be somewhere civilized to prepare spells, in any case. Wizard's lab and all that.)

2) Actually taking up space. No copper coins or weirdly shaped twigs or whatever. No, those are actual heavy items that should, hopefully, matter.

3) Focus on the spell AS the imbued item. You don't "have Fireball prepared", you carry a large piece of volcanic rock. You don't "use Hold Portal", you bring out a fitting lock and key.

4) Flexibility. If you can procure the item, and it's thematically fitting, and it takes up enough inventory space (the spell has to fit!), you can use it. An ice-based spell may use actual ice in a mountain, and night-time oasis-water in the desert.

Number-crunching : How many with class levels among ordinary folk?

I use a really simple formula to figure the demographics of classed characters among ordinary people:

  • A man-at-arms (i.e. someone with just enough training to use armor and weapons) : 1 in 100
  • A level 1 character: 1 in 200
  • A level 2 character: 1 in 400
  • A level 3 character: 1 in 800
etc.


Which means:
1) Characters with class levels are literally the 1%.

2) If you go by 1200s demographics (300 million people worldwide), there are 12,000 name-level-and-up characters worldwide (a single guy holds the record at level 17).
Which seems like a lot, obviously, but scale that back to, say, medieval France (approx 12 million people, largest European country by then) and that's 400 name-level-and-higher characters in the entire country. That sounds good to me.
If you assume 25% are fighters and 25% are magic-users, then there's about 100 lordly strongholds and 15 wizard towers in the country (taking into account the harsher tower-building requirements). 15 guys with the ability to sling 6th level spells in the whole country feels like it's just enough.
Something the size of Languedoc (1/25th of the country's area, approx. the area of the Isle of Dread for comparison) has 4 lordly strongholds and 0.5 wizard towers.
If you go with 1600s demographics you can just double the numbers above (barring the fact that France's population didn't double, plague and all). And have a guaranteed wizard tower I guess!

3) With all of this I can eyeball how many classed characters a location has.
Village with 300 people? One level 1 character, probably a knight and his squire. It took about 150 to fully support 1 trained dude in armor and all that; numbers check out.
A fort like Flint Castle (guarded by 120 men)? Let's say they're half ordinary folks, half men-at-arms or higher. That's 30 men-at-arms, 15 level 1s, 7 level 2s, 3 level 3s, two level 4s, and one level 5.
A large army or really big castle like Krak des Chevaliers or Kerak Castle would house hundreds if not thousands of classed characters and a half- or full dozen of name level PCs. In my opinion, that's alright. Those castles were involved in the Crusades, isn't that perfect high-level-play material?

4) I get to tell my players exactly how rare those hard-earned levels are. Might be cool to know you're a one-in-ten-thousand deal when you finally retire.
