The document discusses the bonuses provided by the Redoubt Tower and Arcane Temple buildings in the game. The Redoubt Tower has shorter range but higher attack, life, defense, and accuracy than the Defensive Tower. It is more resilient against archer units. The Arcane Temple and alliance bonuses can further increase the tower stats up to a 25% boost. Throne room items can also enhance tower stats, applying to both the tower and redoubt.
