Progression

Upgrade a Reinforced Cannon at Eastern Road or later. The branch costs 400 gold after the 180-gold build and 300-gold Level 2 upgrade. Selling refunds 70% of the full 880-gold investment. Earlier-level replays retain their campaign restrictions.

Targeting and impact

The Mortar prefers targets surrounded by the most eligible ground enemies. Shells land at a fixed point; moving targets can escape, while a released shell still explodes if its original target dies.

Combat role

Pair broad splash with Barracks at crowded bends. The slower cadence needs support against scattered fast enemies.

Shared rules

Both branches receive permanent Cannon upgrades. Neither can damage a Wraith during Spectral Form.
