The Sapper unit is a long-ranged siege unit. It is produced at the Barracks tile for a cost of 15. Its movement speed is 3 and it has a vision radius of 4. Each sapper only has 1 hitpoint and fires 1 shot dealing 1 damage.
Sappers are very weak in direct combat, but they make up for this with their extremely powerful Bombard ability.
The Sapper unit moves and attacks as usual.
The Sapper unit has the Focus ability.
The Sapper unit can Capture enemy tiles.
Bombard is a damage ability with minimum range 2 and maximum range 10 (see image). Each sapper fires 1 shot dealing 3 damage.
Note that the maximum range of Bombard extends beyond the vision radius of most units. If a Sapper unit bombards a tile outside of its owner's vision, its owner does not get to see the outcome of the bombardment. Conversely, players that have vision of a tile being bombarded do not see the Sapper unit that is bombarding, unless they also happen to have vision of the Sapper unit itself.
