The Reaver is the siege unit of the Protoss in StarCraft. It is both the slowest siege unit and the most powerful. Unlike most other units, it does not have unlimited ammo. Instead, you must order it to build "Scarabs" at 15 units of Minerals each. It has an initial capacity of 5 which can be upgraded to 10. Each shot uses up one Scarab. Note that the Scarabs move along the ground toward their targets; while they will circumnavigate obstacles if possible, they need a relatively clear path. This and its slow speed are the Reaver's main weaknesses. However, the high damage, splash effect and Normal damage type make it very powerful against groups of weak units such as Zerglings or Marines, and the long range can be used to take out defensive structures with impunity. The Reaver can be upgraded for higher Scarab capacity, higher Scarab damage, higher speed and better armor and shields.
