Encumbrance

Encumbrance indicates the effect that the weight of gear that a character is carrying has on his movement rate. There are 3 levels of encumbrance:

• None/Light- The character can run and walk at full speed.
• Normal-The character cannot run, but can walk at full speed.
• Heavy-The character cannot run, the character walks at 50% normal speed.

The amount of weight corresponding to threshold between levels of encumbrance is dependent on strength and specified in encumbrance.2da. The table is repeated here for completeness:

PnP Comparison

Encumbrance has more severe repercussions in PnP, it restricts a character like armor: including restricting the Maximum dexterity bonus a character can add to Armor Class and introducing an Armor check penalty to skills. Encumbrance is also size dependent, smaller creatures can carry less weight than a large creature of the same strength before becoming encumbered. None of this was incorporated in NWN2.
