Combine

Combine is the action used to make 2 or more items of the same type in inventory into 1, usually to get a heavier item of that type or to overcome the universal container limit of 100. The weight of the newly combined item will be the sum of the original item weights and the quality (QL) will be the average of those of the original items.

Some items that can be combined are iron lump (which needs to be glowing hot for this), wood scrap (very usefull when feeding ie. forges with them), rock shards, cotton, clay etc.

To combine 2 items, activate the first item then right-click the second item and select "Combine".

Entire groups of identical items can be combined in 1 action by activating the second (or later) item in the group, right-clicking the group line (the one with a -/+ sign) and then selecting "Combine".

Note: Combining will reduce the total monetary value of the final product if they are not all of the same QL. Combining uses a linear average but the prices in Wurm are not linear but, instead, quadratic (so a quadratic sum would be more accurate than a linear average).
