Having dug a little deeper into the MM3, it turns out the yugoloths came out better than we had originally been led to believe.
Yugoloth is now officially a subtype. Woo-hoo!
- The canoloth gained a HD and boosts to ability scores, and went down a CR.
- Same goes for the mezzoloth, who also gained a caster level boost, a magic trident and now has its shield figured into its stat block.
- Nycaloths gained 3 HD, a liftoff ability, and its CR went down by 3. They also added the nycaloth commander, a nycaloth advanced to 25 HD.
- Although its Intelligence is still woefully low, the ultroloth picked up a +3 longsword, 5 HD, 100 hp, several more at-will spell-like abilities, a higher caster level, and its CR dropped by 3. Oddly, the ultroloth has a LA of +5, which combined with its 18 HD, pushes it past the "glass ceiling" of ECL 20.
Other MM3 Observations:
The first monster I used (the storm elemental) had several errors. On the save DC tables for its abilities, the elder and greater elementals were reversed. The nycaloth's grapple modifier doesn't include its strength modifier, and it lacks a caster level for its spell-like abilities.
It is still riddled with the usual cut-n-paste errors. The mezzoloth still uses teleport without error, for example.
The inclusion of "preset" Power Attack in the stat block is maddeningly frustrating. I hope they ditch this quickly in future supplements.
Telepathy is back in the combat sections of critters, instead of referring to the glossary.
Spell-like abilities are no longer italicized in the bold part of their entry. They've dropped "the save DCs are Charisma-based" from the end of spell-like ability entries.
They have dropped the "This ability is the equivalent of a x-level spell" from summon entries.
Old-school wounding has been renamed "bleeding wounds".
