Stomach Striker
From Warbirth Wiki
Stomach Strikers are unique Asian ships, which are specialised at ramming. These units, considered as heavy shipping, are highly lethal at close range, and are best used to clear out large concentrations of light ships, such as War Boats and Triakonters. Available in the Heroic Age, these units are still vulnerable to Fire Raft attacks, and also have poor attack speed, so they are best used only in cycle attacks (a delay of exactly 99 ticks), but their fairly cheap cost, if compared to units such as Triremes and Biremes, can make all the difference. Later, they can later on be upgraded to the all-famous Tower Barque, creating a more powerful unit.
