Armor check penalty
Armor check penalty (ACP) is a penalty to some skills due to the restrictiveness of certain armors and shields.
The following are subject to Armor check penalty:
Armor check penalties from armors and shields stack.
Non-proficiency penalties[edit]
ACPs always apply to your skills. Non-proficiency with an armor or shield causes its Armor check penalty to apply to your attack rolls as well.
Carrying capacity[edit]
Carrying capacity also can cause an Armor check penalty.
- Medium encumbrance causes a -3
- Heavy encumbrance causes a -6
Note that medium encumbrance does not give any visual feedback, except that you run slightly slower. This may lead to unexpected deaths while swimming.
Reducing armor check penalties[edit]
Armor and Shields[edit]
- Mithral armor and shields have reduced armour check penalties (usually by 3).
- Nimbleness reduces armor check penalties by 2 or 4.
Feats[edit]
Other items[edit]
Enhancements[edit]
Note that light armors have a base armor check penalty of 0 (leather) or 1 (chain), so reductions beyond this level do nothing. Enhancements with reductions to armor check penalty usually increase maximum dexterity bonus as well; reducing the check penalty is just a bonus effect.
