Sappers are a Goblin unit, designed to do maximum damage at the cost of the units lives. They tend to be used to do damage to stationary structures, targets where they do devastating amounts of damage! However, if any units are in the surrounding area when a sapper self destructs, they can do enough damage to effectively kill them as well!
Sappers may be bought from Goblin Buildings, such as the Goblin Laboratory, although these are not available on all maps. They act much like other mercenary units are appear immediately once the correct amount of Resources are paid. They will also take up some Food slots.
