Found another thing with the packlord.
One of its rage powers is "swift foot +5 feet." That means its speed should be 45 ft while raging. Not 40. Though that should be listed in the Base Statistics section.
....and the packlord has "mwk javelin +11/+6" listed as a ranged attack. However, the packlord only has one javelin listed in its gear.
Pg. 45 - Ironskin spell
This spell says the bonus to natural AC it grants increases by 1 for every 4 caster levels above 4th, to a maximum of +7 at 15th level, but that math doesn't check out (it would cap at +7 at 16th level instead). Given that full casters have access to this spell, starting at 3rd level, it probably meant to say it increases by 1 for every 4 caster levels above 3rd, which would cap at +7 at 15th level.
