Belt of the Ox, Legendary

is an Artifact item. This belt grants additional Encumbrance Capacity, but it inflicts a Move Speed penalty. Tier level does not effect the move speed penalty (e.g. common & epic have the same move speed penalty). The Encumbrance Capacity buff is applied to your base carry capacity (i.e. the amount you can carry when all other non-strength encumbrance buffs are excluded).
