The Siege abilities describes that a unit deals bonus damage to buildings and is therefore predestined to make quick work of dangerous towers and spawn buildings in PvE or Wells and Orbs in PvP. The baseline is a 50% damage bonus but there are certain units that exceed that.
For some units only the fire affinity has Siege, while the other has a different ability.
