That organization works for me.
Which one, solitary or pack?
In honour of my semi-plagiaristic ditty I'd like to propose changing pack to family:
Organization: Solitary, pair or family (3-6)
Getting back to skills, +8 racial bonus on Hide?
Hide 4, Listen 2, Move Silently 5, Spot 2?
Let's see, with its stats, +4 racial on Search & Spot and +8 racial on Hide that adds up to:
Skills: Hide +10, Listen +3, Move Silently +7, Search +5, Spot +7
Those look fine to me, let's make it so!
That only leaves Challenge Rating, doesn't it? I'm thinking somewhere in the region of 6-7. They're mean up close but can't hurt you from a distance. I'm often uncertain about CRs, what do you fine persons think?
