Nice Listen check result!
Improved Initiative or Weapon Focus appeal for the smaller two, and Iron Will for the calipha works as well.
Combat Reflexes is of limited use to a creature without Reach, of the remaining options I'd prefer Weapon Focus (greatsword).
Full ranks in Spot and Listen for the Warriors?
We need to add another maxed out skill (or an equivalent point division) for the Nobles.
Maybe Knowledge (religion) and Knowledge (architecture and engineering) since they spend all their time worshipping their Calipha and building her a palace?![]()
I can support all that.
Pasari-nimal are immune to all spells of the charm or enchantment schools.
A calipha exists to eat, receive worship, and reproduce. She has a beautiful, if small, female human head with long tresses and large, feathery antennae. Unfortunately, this spark of beauty is situated on an ugly, mottled, wormlike body.
The calipha has only a weak bite to defend herself, and her legs are small and weak. She cannot use tools, and she moves by wriggling.
Diplomacy, Sense Motive? Split the remainder between Listen and Spot?
Negotiator for the second feat?
I'm OK with all that, except I'm shifting a rank from Diplomacy to Sense Motive to trigger the synergy bonus to Diplomacy. Net gain!
Updated.
We've still got some "x"s and question marks in Pitfall...
The pasari-nimal cut and pry at armor to make a hole, which takes 1-2 rounds. Afterward, a single pasari-niml attacks the vulnerable area at each hole.
Updated.
Should we give them Improved Sunder as a bonus feat? Or some form or armor-destroying ability like a bebelith (usable only against those trapped in a pitfall)?
