For the most part, it looks like you have your highest level spell costing 8 points (or 6 on even levels) and each level below that it is half the cost. Also, you start with 32 points, which means you can cast your best spell 4 or 5 times depending on your exact level.
How is this any different than having the SP cost of each spell level simply double while doubling the SP a caster gets every odd level? It should work out the same. For example, take a SP cost progression like this:
Spell SP
Level Cost
0 0
1 1
2 2
3 4
4 8
5 16
6 32
7 64
8 128
9 256
And then have a SP per caster level progression like:
Caster Total
Level SP
1 4
2 6
3 8
4 12
5 16
6 24
7 32
8 48
9 64
10 96
11 128
12 192
13 256
14 384
15 512
16 768
17 1024
18 1536
19 2048
20 3072
I can see an aversion to a system like this because the numbers are a bit higher, but it still holds to the doubling principle. I guess personally speaking, I find a system like this more intuative, but it should be pretty similar in implementation to yours (with doubling "effective" costs). So, while I think this version is more intuitive, I think yours might be more simple mathematically speaking.
Whatever our collective opinions of a spell-point casting system or psionics, I think we can all agree that they need work. In fact, I don't think any of them work. At all. Ever.
For the most part, I actually think psionics is a pretty solid system, at least compared to standard casting.
Again-this is asking balance questions about the given work. I'm responsible only for posting it here.
Well, I'm a little iffy on simply doubling costs. Basically, it means you get 256 1st level spells per 9th level spell. I guess by the time a standard PHB caster gets to 17th+ level, they already have ways to cast tons of 1st level spells anyway, so maybe it doesn't really matter.
As an aside, can anyone tell me how to get the url tags to work properly. They seem out to get me today. Thanks!
