In the game's words

How to use it

The Light Cannon is a land-based siege unit with a long range. Its attacks can do peripheral damage to units and objects near its target. It's good against artillery, infantry units, and buildings. It is available from the Siege Workshop in the fourth Age or from the Tribal Council.

History

Most Haudenosaunee campaigns ended up with siege warfare. This fact, combined with the Haudenosaunee predilection for modern weapons (trade steel and gunpowder), meant that they learned to deal with military technology early in their history. The cannon was a natural step in this development. The Light Cannon represents an artillery piece, bought or stolen from European allies, but crewed by Haudenosaunee warriors.

Counters, worked out

Armies of equal cost, base stats (no upgrades or cards). "Edge" = how many times the winner's spending the loser would need to draw. This unit hits an area, so one-on-one figures understate it against groups.

Beats Light Cannon

How this is worked out

Each hit: damage × every multiplier that matches the target's types × (1 − the target's resist to that damage). Two ranged units trade shots; against a melee-only unit the better of ranged and melee is used. Damage per second = hit ÷ seconds between attacks.

Armies bought with the same resources fight by Lanchester's square law: strength = (resources ÷ unit cost)² × damage per second × hit points. The edge is the square root of the strength ratio. All matchups.
