Spell Law Deconstruction: Building Spell Lists to 50th lvl.

Image result for spell law

Now that I’m posting up some more spell lists–Mentalism primarily, I’m tracking comments and feedback on the forums and here at RMBlog. The number one issue I see is the desire for spell list reductionism, maybe build 10 spells per “list” and allow for creative scalability similar to or identical to HARP.

That is a compelling thought, but after writing a ton of spell lists I wanted to put my own thoughts in order.

  1. Distillation. Rebuilding classic RM spell lists typically requires some trimming. Many spells within a list are redundant: not just the spells that progress as I, II, III etc, but different named spells that do similar things. Distilling the essence of a list can really reduce the total number of spells which makes a scalable spell system very appealing!
  2. Spell scope. I’m not a fan of kitchen sink style spell lists, but do see a fundamental difference between the realms. Essence should be very tightly focused around a key aspect, Channeling should allow for much more variability based on the particular god and I see Mentalism lists following a shared mental mechanism. Using these basic rules provides different ways to build lists in different realms.
  3. Compatibility. A major motivation to maintain the 1-50th spell lists is basic compatibility with RM and Shadow World.
  4. Built in scalability. Many of my lists are built around 3-6 spells, that progress from I-V and maybe include a mass effect. If each spell repeats every 5 levels that takes up a chunk of the list, but also gives a repetitive appearance that seem suitable for scaling. However, the spell versions don’t just scale progressively, but change in target size, AoE, Range and other aspects that provide “more bang for the buck”. General scaling assumes increased power point cost/expansion of range, area, damage etc. So from an efficiency standpoint, higher versions of the spells in BASiL provide a better impact/PP than just linear scaling. “Spell II” isn’t just 2x better than “Spell I”, it can be 3x better or have expanded efficacy or powers as well.
  5. Opportunity and tactical cost. By having built in scaling, players can use higher or lower level spells based on the target, PP consumption and risk/reward calculations. Of course, that’s also one argument for Scaling spells, but the PP usage will be much different per #4 above.
  6. Level assignment. One of the more difficult aspects of designing a spell list is deciding what level to make a spell. Part of me wants to calculate an estimated “power cost”, while other times I’m thinking of utility and game balance. For instance, the big three: Charm, Fly and Invisibility can be very unbalancing to the game, but perhaps shouldn’t be based on “power needed” or some other arbitrary assessment. Some lists just can’t be distilled into 10 spells with scaling options. Some spells need to be higher level to reflect their real power and also make them unavailable to lower level players.
  7. Vertical versus horizontal acquisition. RM (and probably RMU) is build around horizontal model of spell acquisition. Generally players will know more spell lists than overall spell levels. For instance, a 5th lvl caster may have access to 5-10 lists but can only effectively cast to 5th level without risk of failure. In BASiL, it’s the opposite. I use a levelless system so players generally know a few spell lists to higher level. That gives them more powerful, niche abilities. It’s just the way I like my game to run–hard specialization versus the generalization of RAW.
  8. Keystone spells. I still like cool spells that can be found at 10th, 20th and certainly 50th level. I try to add something unique or interesting at these levels for players to look forward too, or to give the list a “bump”!

I guess sticking with RM I wanted to improve on the originally 35+ year old Spell Law and incorporate spell ideas and powers introduced since then. But if I were to start over, I would take a hard look at a HARP scalable system. Or maybe just use HARP rules?

Many of you also build your own spell lists. Do you have build guidelines, mechanistic philosophies or other design criteria that help you in the process?
