I'm not 100% whats as intended but here is a few thoughts anyway.
Both the (Archer) and (Warrior) "Skeletal remains" items produce skeletons properly, however.
The archer is equipped with a longbow and ( a very short supply) or arrows
The Warrior is equipped with a shield and longsword.
Both get Weapon focus and Specialization battleaxe, alertness and disarm
The archer also gets weapon spec Longbow, Rapid shot and called shot
The warrior also gets Expertise.
Might I make the following suggestions, given this.
Remove The unused specialization for battleaxes and add them for the Longsword on the warrior and weapon focus for the longbow on the archer.
Allow the archer to have a larger stock of arrows (even basic) before It reverts to its creature weapon.
It would also be nice to see the warrior have exotic weapon proficiency.
In return for the minor boosts to strength it might be advised to remove the.. "Deadly fog" affect as this is more of a zombie thing anyway.
You can give a different weapon to both parties, AND you can load up your archer with ammo. You will find that different undead have different capabilities.
Adjusted.
