This is a situation that came up recently while GMing the Pathfinder Module "Crypt of the Everflame."
A character's strength was reduced to the point where he was in his "heavy load," which imposes a "check penalty." The Core Rulebook says:
Like armor, a character’s load affects his maximum Dexterity
bonus to AC, carries a check penalty (which works like
an armor check penalty)...
(Additional Rules: Carrying Capacity, Page 169)
Now, a character who is not proficient with armor takes double the armors check penalty to their attack rolls. Does this mean that a character who is in their heavy load takes -12 (double the check penalty of -6) to their attack rolls?
Does this sound right, or is there an errata, or thread somewhere that addresses this?
