[Circûmflex] Messing around with spellpoints in an OSR-style system

snowwhite20

This last week I have been sick. With lots of time on my hands I have been working on a version of Labyrinth Lord that is more suited for playing on HârnWorld. By now the whole thing does not look much like Labyrinth Lord anymore. Although it still is pretty close to the mathematical values, and more of a homebrew than an actual new system. I call it Circûmflex, because if you know Hârn, which is like calling something D&D-connected Ampersand.

These posts will be basically meditations on why I decide to do certain things one way or another. Please feel free to comment, especially if you know more about the maths of games than I do (which is not hard).

In any case, one of the things I decided to overhaul was the magic system. I adore the Vancian magic system, I really do. But it just is not a good fit for the setting I intended this to be played in.

So I started to fiddle around with spell points a bit.

One idea that was floating around in various places was that one could just use the number of spells wizards gained per level, and give them a value of points per level, connected to the Fibonacci sequence. I liked that. It made lower level spells cheaper, while making more powerful spells more difficult to cast.

Piety and Mana

To use spells and invocations wizards and clerics use a pool of points each. For clerics this is called Piety, for wizards this is called Mana. Both are determined by the level of the character, modified by the modificator for Wisdom for Clerics, and the one for Intelligence for Shek-P’var.
Mechanically they work almost the same. A spell or invocation of a specific level has a cost in piety or mana. When it is invoked or cast it reduces the amount of points by the set amount. When the pool of points reaches 0 no further invocations or spells are possible until they are replenished.
If the last spell cast would bring the pool of points under 0 the cleric or shek-p’var has to Save against Spell. If this roll fails he/she might incur the displeasure of their deity (cleric), or the spell might misfire (according to GM’s fiat). In any case the cleric/shek-p’var will feel burned out and not be able to invoke/cast again until at least half the pool is replenished.
Piety and Mana points replenish at a rate of 1d8 per night of rest spent in prayer or meditation.

The cost of spells and invocations is determined by the level it has. At level 1 it costs 1 point, at level 2 it costs two points, at level 3 three points, at level 4 five points, etc.

Some notes on that:

  • I renamed spells for clerics to invocations. This is in line with the terminology in HarnMaster, even though in this case it does not make any difference ruleswise. Likewise I used the word Piety, which has an actual value in HM, to denote something completely different. The word Mana does not even appear in HM I think, but I am trying to dress Labyrinth Lord in the right guise, I don’t try to emulate the rules of HM.
  • Wizards are of course Shek-P’var in HârnWorld. Technically Shek’P’var are just the most common and widespread of wizards, and there are quite a few hints towards other traditions, but I will go with that right now.
  • The spellpoint management is actually inspired by older editions of Das Schwarze Auge (The Dark Eye). I don’t know if newer editions still have it (5th edition just came out and I haven’t even seen a book of it yet…), but I felt it might fit the setting well if spells cannot be easily regained from day to day. Mana and Piety in this system replenish at about double the rate as hit points. Which means that spellcasters start pretty strong, but have to keep their resources in mind better.

Ah yes, about that last part…

This is the point when I decided to have a look at the amount of spell points available to my spellcasters. Now, I have to add here that in the previous version of my houserules I decided at one point that all the levels I really needed to think about was the ones up to level 12. In the last few years barely any of my players managed to reach even these lofty heights, and I mean the years since I started playing AD&D 2nd edition back in the 90s.

Funnily enough I noticed something interesting when I calculated the spellpoint equivalents to the usual Labyrinth Lord spell slots: if I calculate according to the Fibonacci sequence I mentioned earlier, with one 1st level spell as 1 point, and 1 6th level spell as 9 points, at level 12 I reached exactly 66.

If I would let that go on further the Quadratic Wizard effect would of course be in full effect. That was one of the things I found was easier to avoid with a soft level limit of 12. But even like that, this is pretty strong, isn’t it? Especially considering that I was already thinking of getting rid of spell books and memorization. Kind of strong for the nominally low-magic world Kethira.

On the other hand I was toying with another idea: why not give spellcasters a roll for their spell pool that is equivalent to their hp pool?

Well, ok, because people might hate not having a clear level progression, and because bad rolls happen (although I do have an idea to mitigate that) and because it would benefit some people but not others. But other than that?

I actually did see something similar in Das Schwarze Auge. True, there the system actually started with 25 or so “astral points” and leveling added to that, but DSA always was a bit of a slugfest with all those points. So lets say we start with a mana pool of 1d8 for shek-p’var, and 1d6 for clerics. This still might be too much actually. This would give an average of 4.5 points, plus Int-mod. At the top of the range this might mean a wizard could have 11 spells a day on first level. Hmm. Nope, not good.

Ok, lets go with 1d6 for both. this would give an average of 42 points, a minimum of 12, and a maximum of 108 spell points on level 12.

I gave the Shek-P’var a requirement of Int 9, so no negative modifiers should be possible. After all one needs to be at least able to read to study old musty tomes of arcane secrets. No Int 3 wizards in this system. Sorry.

Ok, a super-genius wizard who can spam 12 level 6 spells on level 12. A bit over the top, but doable. On the other hand even someone with the worst possible kind of luck and no modifiers should be able to blast off at least 12 spells at once.

In this case it actually might help that either of these wizards only get back a maximum of 8 points per day.

Luckily, there are some limitations for both clerics and wizards in this setting. Clerics only have access to a limited pool of spells. Some of the spells, sorry, invocations, might be downright useless from an dungeoneering point of view (which is okay, there aren’t that many straightforward dungeons in the setting anyway). There is not really a reason to invoke “Marriage” for example, except to replenish piety points. And where do you find a willing couple in the middle of the dungeon anyway?

Ah yes, that latter one is an actual invocation from HarnMaster Religion. There it of course makes a lot of sense. The clerics in HarnMaster are not only walking hp-fountains. In fact a lot of the gods don’t even have healing invocations. But doing some good work like baptising new adherents, and performing weddings for others, actually increases the piety for the priest. This would not actually have much sense with the usual Vancian magic, it does make more sense if clerics have to replenish their piety somehow.

Wizards actually have it a bit better, at least in higher levels. The Pvaristic system the setting has actually keeps wizards from having access to all the cool spells at once. A shek-p’var starts as a specialist in one of six convocations. This means he for example only has access to water-aspected spells. But shek-p’var can attune themselves to the other convocations the more experience they have. So over time they can gain access to all convocations. Or they just stay a specialist in their field. Whatever floats their boat.
