Looking at the skills, I'm wondering, where does the Jump +10 come from? Is that an unlisted racial bonus or a special abiilty I'm just not seeing for some reason?
The original's Jump has +2 from Strength and +8 from its 50 ft. speed.
It should now have +12 due to its higher Strength score, but I haven't adjusted it yet.
Anyway, we could distribute the 22 ranks as Hide 5, Listen 6, Move Silently 5, Spot 6. I don't think Jump or Swim necessarily need more.
I reckon we ought to give it at least the same skill modifiers as the 3.0 original, which has Hide +9, Jump +7, Listen +8, Move Silently +9, Spot +8, Swim +7 plus Alertness.
That works out as skill ranks Hide 6, Jump ?, Listen 4, Move Silently 6, Spot 4, Swim ?, which leaves us with 2 skill ranks in our budget.
Splitting those between Listen and Spot seems to make sense.
Since we're keeping Alertness like the original, that'd mean it has:
Skills: Hide +9, Jump +12, Listen +9, Move Silently +9, Spot +9, Swim +12
Any preferences for the other two skills? I'm thinking we should make one of them a Psionic feat, and maybe Weapon Focus (bite) for the other one.
