Unearthed Arcania is one of those supplements that I found later in my gaming career that I wish I had found much earlier. For completeness, I also would have liked Rhyme of the Ancient Spelljammer and Temporum Sphaera. (I currently have all three now.) Sometime ago, I also found a netbook called Wizard's Netbook that provides all kinds of spellcaster variation. I could list a lot more of them, but if you remember them at all, you probably have all the same ones I have.

As an aside, do any of you have the Spell Markup Language?  Fun to read...

Anyway, there's something about the wealth of the house rules that inspire all kinds of creative possibilities. I plan on adapting a well playtested spell point variant to the OSR Project. Spell points available would be properly notated like this:

and add 1 to the result.

The spell level limitation will be per the Microlite 20 Core Rules - Spells can be cast with a spell level equal or below 1/2 a spellcaster's level, rounded up. The cost to cast a spell will be 2* spell level. Cantrips will cost 1 point. Owing to my OSR ways, all of this information will be presented in a chart that looks something like this:

Level Spell Points Max Spell Level
1 2 1
2 4 1
3 7 2
4 11 2
5 16 3
6 22 3
7 29 4
8 37 4
9 46 5
10 56 5
11 67 6
12 79 6
13 92 7
14 106 7
15 121 8
16 137 8
17 154 9
18 172 9
19 191 9
20 211 9

For those that wonder, this makes them weaker than standard spellcasters - the effect is that noticeable until around 10th level or so. As a result, the XP required to advance to the next level is approx 10% less than a standard spellcaster. Debate now swings around Meditation in lieu of sleep. Basically, 3 hrs meditation = 8 hours sleep.

More later.
