The D&D Monster Conversion Thread

[robertsconley]

I recommend looking at the list of monsters included in Swords & Wizardry Core edition as a starting to figure out which creatures to convert first. And covert any missing creatures from that list first using the d20 stats as a guideline.

That will cover just about all the core D&D monsters. From there the remaining d20 monsters can be converted.
