All done, then?
Ok, 3HD. Looks like Str is pretty decent (could stick to 14-15 for the +2 to damage, but I think it would be fair to bump in the conversion). And a 1d6 bite. Nothing else to speak of, I guess.
Works for me.
While that makes some sense, it would seem to support 6 attacks (2 per "arm"), which is too many for such a low-CR creature. Also, multi-pronged attacks (like the scourge) have a precedent as a single attack in 3.5. Let's just go with 2 and call it a day.
Updated.
Rereading the original description it has 2 arms (1d6 damage) and a bite (1d4 damage) in the first place. How on earth did we get so confused?
