The awesome Maug from the Fiend Folio

[Wolfix]

I came across this hulking construct and was immediatly impressed by it, so I'd like to use it. Seems kinda strong for a CR3 though, right? Anyway, what I wanted to ask: I can't make sense of it's attack bonusses. Both the slam attack and the twobladed sword attacks seem to be wrong. Am I right about this or am I missing something?

Looks like an error in the statblock, yes.

Let see...

BAB +1 (2 Construct HD).
Str bonus +5 (20 Str).
Masterwork sword: +1.
Large size: -1.

So for the single attack, the Maug should have +6 with the two-bladed sword, and only +5 for the slam attack (no masterwork enhancement bonus for them fists).

And, with the TWF feat and a double weapon, he should have a full attack of +4/+4 with the 2B sword.
