Since Season Nine, Culverins fill the same role as the Bombard, functioning as an anti-building siege unit. They are slightly more mobile, not having to pack or unpack, but cost slightly more. They also have a faster rate of fire and slightly more range but do less damage per shot, for an overall slightly smaller damage-per-second (DPS).
However, for the French and Jeanne d'Arc, the Royal Culverin have to compete with the Royal Cannon for the same role. In this regard, the Royal Cannon deals significantly more DPS than a Royal Culverin against buildings while also being faster. However, it has less range and health and costs slightly more. It also does deal less DPS than a Royal Culverin against infantry. If trying to destroy buildings, the Royal Cannon is almost always the better choice, but the Royal Culverin may be more advantageous against large infantry armies.
Originally, Culverins dealt 35 damage. With patch 12.2.3327, they deal 40 damage.
Originally, Culverins dealt +230 bonus to ships, +230 bonus against buildings, and a +50 bonus against infantry. With patch 12.1.2454, the bonus against buildings was reduced to +215 and they gain a +35 bonus against elephants.
With patch 12.1.2454, Culverins gained the attack ground ability.
