I am making a place in space-time for time lost B/X cosmonauts to come to earth.  It's getting pretty involved. Keywords: heavy metal, halloween, ice-age, apocalypse.
That said, there is nothing terribly ground breaking or original here. Each of the classes below is more or less a reskin of a B/X class with minor adjustments. As for the art, it is is all mine, but some of it needs to be redone- the leech art is particularly weak, for example.

Edit: it says majus once where it should say Rat (for awhile I had a different name for these guys) and the Rat progresses and saves as a B/X magic-user.

Last one.

Neat.

Maybe it's just me, but contrary to what S&W does, I think if you are going to use ascending AC (AAC) where 9 is no armor, it should still be subtracted from 20, not 19, and thus the armor class of 4 should be 16, not 15.

Why?

Because otherwise 0-Level characters would have a negative attack bonus.

a 0 level character needs an 11 to hit Descending AC 9 in B/X D&D. If DAC9 = AAC10, then his attack bonus would be -1.

On the other hand, if it's 11, then his attack bonus would be zero. And then PCs would start off with a +1 bonus at 1st level, instead of 0.

Similarly, if you start from 20, you can simply use the HD of the monster as the attack bonus.

In BX 1 HD monster hits an unarmored (DAC9) on a roll of a 10. So if you set the AAC to 11 for unarmored, then it's identical. OTOH, if you start it at 10, then a 1 HD monster would have a 0 attack bonus.

Looks good to me, but I actually use descending and the chart in Expert.

Sweet. Dibs on the party Rat.

Cool!
