The ballista is a powerful weapon that can be found on either team's Castle and around the map in Happy Wars. When mounted, press [RT] to fire and [X] to reload. The ballista holds up to 48 arrows in one magazine without "Cannon Shots" upgrades. However, ballistas are very fragile and without "Cannon Durability" can be destroyed by a single Mage's lightning strike so a Cleric is advised to mount the weapon as it will need repairs frequently. Buffs that specifically increase ballista and Flower Cannon effectiveness include "Cannon Accuracy Up," "Cannon Shots Up," and "Cannon Durability Up." Other buffs that go well with a class for Ballista or Flower Cannon utilization include "Slayers," "Anti-Materials," "AP Damage Attack Up," "Smash Power Up," and especially "Tactical Up."
