Walkthroughs for custom maps.

The Month of Plague is something that cannot be programmed into a map (for SOD, of course), so avoiding the Month of Plague is a challenge in any way possible.

I wouldn't say that. I don't know how it's done, but there are maps where weeks of the same monster constantly repeat. Or, for example, the map of Ira the mage, where in 2000 (!!!) months, there wasn't a single month with a monster. Apparently, by combining objects on the map, it is possible to achieve a guaranteed effect (of not) spawning certain weeks or months, including the Month of Plague.

I'll get around to looking at the code for generating weeks and months someday, but that's not certain.
