When modifying the existing Monster Manual Creatures, specifically reducing CR you need to consider a lot of things. With these elementals their size needed to be reduced from Large to Medium. This effects their hit dice (from d10s to d8s) their damage dice from 2 to 1 respectively and their ability scores.. which requires a bit of DM discretion. I reduced their physical attributes down slightly and left INT/WIS/CHA alone. The DEX reduction affected AC on the squishier elementals. But I did not let it affect the AC of this earth elemental because it’s still well armored.
Hope you enjoy this one! I’m taking requests on other monsters that the audience would like to see home brewed.
