Aberration Attack Bonuses

[Quidam]

In the advancement section of the MM, it states that an aberration's attack bonus = 3/4 it's total HD. And yet, scanning through, all the aberrations I've checked have one less. A 6HD aberration should have an attack bonus of 4.25, rounded to four, but I'm seeing bonuses of 3. Same for other HD aberrations.

Is there some errata I'm missing or something more obvious that's slipping under my radar?

(edit)

...and while I'm at it, the saves- as cleric?- seem off, too. I'm specifically looking at otyughs. The fort save is supposed to base at 5 but an otyugh's fort is 3.

Have you counted in size penalty ?

 

[AuraSeer]

I dunno about the saves, but the Otyugh's attack modifier looks right to me. Are you including the size modifier? Its tentacle attack is at +3, which looks like 4 (base) +0 (strength) -1 (size).

 

[Quidam]

D'oh! I'd forgotten- I'd thought the size penalty only applied to AC.

Thanks!

Still doesn't answer the question about the saves, though.

(edit)

Though looking at pg 22 of the PHB does. Don't mind me. Nothing to see here...
