alter weight [item] alter value [item] alter capacity [item] alter name [item] alter remove [item]
Merchants can alter an item so that it either weighs slightly less than before or its value increases slightly. This can only be done once per item.
At level 35, High Mortal merchants can also alter the name of an item to be that of a non-descript general name for that item type. They can also increase the carry capacity of a container.
A toolbox is needed for this skill.
You can remove alterations from an item. It requires 40 parts from a toolbox to remove an alteration.
Note: Some items' stats cannot be altered for various reasons.
