Holmes Expanded: Balrog to Zombie

For my expanded monster list, I included all of the creatures with stats appearing in OD&D + Greyhawk, as well as most of the new monsters appearing in The Strategic Review (only leaving out the Denebian Slime Devil).

For aquatic monsters mentioned in OD&D vol. 3, I used stats from the Blackmoor supplement, and for monsters provided with only partial stats in Greyhawk, I consulted the AD&D 1e Monster Manual (the source of some creatures for the 2nd printing of Holmes).

The following list includes all of the monsters from the 3rd printing of the Holmes rulebook, supplemented with everything from OD&D + Greyhawk as well as The Strategic Review and can be used with the wandering monster tables from Greyhawk and Eldritch Wizardry:
