Any armor heavier than leather, as well as any shield, hurts a character's ability to use Dex- and Str-based skills. An armor check penalty applies to all Dex- and Strength-based skill checks. A character's encumbrance may also incur an armor check penalty.
So if I have a character with hide armor that has a Armor Check Penalty of -3 then, for instance, I would take a -3 on my Climb skill which is based on strength and also on Stealth which is based on Dexterity. Am I understanding this correctly?
If I am correct then I assume that there are Combat Feats that will allow characters that have them to ignore a portion or all of the penalty. Is this a correct assumption?
