The Slavs also lack both Faith and Heresy, and due to the Slavs' dependence on siege weapons and expensive units like the Boyar, this makes the Slavs incredibly vulnerable to the Spanish and the Aztecs, which have strong monks. While they have powerful infantry their archers are weak as they don't have the Arbalest and Bracer and are missing some other archer upgrades such as Thumb Ring. Their cavalry is somewhat lacking as they don't have the Paladin upgrade but they make up for this with their unique unit, the Boyar, a cavalry unit with heavy melee armour that can be used as a damage soaker for other units.

They have powerful infantry units as they have all infantry upgrades and their second unique technology, Druzhina, gives infantry AOE damage, making them powerful in groups and against clusters of units. They have cheaper siege weapons due to their civilization bonus.

Their Monks are tougher than most because of their first unique technology, Orthodoxy, which gives them +3/+3 armour. Detinets is a technology in Age of Empires II: Definitive Edition - Dynasties of India that is unique to the Slavs and can be researched at the Castle. They have a good economy, missing only the Stone Shaft Mining and Guilds upgrade. Slavs are an offensive, economic civilization with powerful infantry and siege weapons.
