AI Description

At the start of this Faction’s Turn, this Spire will Attack a Spire or Fortress Gate within its Range if possible. If it has multiple Target options, its Attack priorities are an Opposing Fortress Gate first, or, if that is not in Range, the Opposing Spire with the fewest Upgrades. After this Spire attacks a Fortress Gate, remove its bottom upgrade.
