God's Own Sling appears as a Trebuchet, but has a few peculiarities. When unpacked, it behaves like a normal hero, it cannot be converted and regenerates itself. Still, even unpacked, its armor remains the 2/8 unlike with regular Trebuchets, which have 1/150 in the unpacked form. Unpacked, God's Own Sling has 300 HP. Packed, however, the hit points drop to 150 (the actual number is halved, so if e.g. a God's Own Sling with 233 HP packs itself, it has 116 HP in the packed form) and all hero qualities are lost, so it does not regenerate anymore and can even be converted. Furthermore, the packed God's Own Sling has a melee attack of 1 which it can never use, though, as it instantly starts unpacking when ordered to attack. Both versions can be repaired by Villagers.
- God's Own Sling was in reality named God's Stone Thrower. Alongside the Bad Neighbor, they were used in the Siege of Acre, but are erroneously available to Richard the Lionheart, as in reality, they belonged to Philip II of France, the king known for transforming medieval France into one of Europe's most powerful states, and a participant in the Third Crusade.
- The range of 20 (which it ties with Bad Neighbor) is unparalleled in the game.
