The Encumbrance of an Item is the awkwardness of the combined size and material of goods.
Encumbrance Capacity (EC): The maximum Encumbrance you can carry without it affecting your activity. A character without measurable Encumbrance CAN be Unfettered if they meet all other requirements.
(Load/Encumbrance < EC) No Movement penalty (incl. from Exhaustion), no Armor, nothing held, no targeting barriers (helmet)/no muffling of sound.
(Load/Encumbrance >= EC) No Movement penalty (incl. from Exhaustion, but not Difficult Terrain), Proficient in Armor worn, one arm free, basic line of sight and hearing unobstructed,
Direly Encumbered: Enc > EC x2
= half movement, disadvantage on initiative; disadvantage on Stalking, 2 measure of exhaustion
(Load/Encumbrance > EC x5 )
Non-proficient with aArmor/Shield/Weapon; senses directly impinged, [normal] Movement reduced (incl. from Exhaustion, but not Difficult Terrain)
Disastrously Encumbered: Enc > EC x
= Maximum movement of 5’, disadvantage on initiative; disadvantage on Stalking, 3 measures of exhaustion
All items they use must match the character’s Size (Factor). If not, worn items cannot be worn effectively at all, held items increase by +1 ENC per category greater. If you do not meet the minimum attribute rating for an item = +1 encumbrance per condition unmet.
