Use 10 Etherian Mana to summon more than one
The Ballista Rod, Cane, and Staff are special sentry summon weapons that summon a Ballista sentry minion at the point clicked. Each Ballista sentry is a large automated crossbow device on the ground that fires piercing spears at approaching enemies. The Rod is sold by the Tavernkeep for 5 Defender Medals, the Cane for 25, and the Staff for 100.
The Rod is always available. The Cane becomes available after defeating one Mechanical Boss, and the Staff becomes available after defeating Golem. The three different versions cause an identical effect, but with varying statistics, with the Staff being the most expensive and the most powerful.
During the Old One's Army event, Etherian Mana can be collected, which allows the placement of multiple Ballistas that remain permanently until the event is over. Etherian Mana cannot be used outside the event.
Its best Modifier is Ruthless. The Mythical modifier presents a wider array of stat bonuses, but most of these apply to the initial summoning, and not to the resulting Ballista. Additionally, Minions cannot deal critical hits. The only significant advantage the Mythical modifier has over Ruthless is in knockback.
Ballista sentries are boosted by the Squire armor and Valhalla Knight armor set bonuses, which grant Ballista Panic! when the player takes damage. Ballista Panic! doubles the fire rate of Ballista sentries for 3 seconds after taking damage.
Right clicking an enemy or near the enemy will make the Ballista Sentry target that enemy. When targeted, the enemy will have a purple glow around it. The purple glow will be caused even if the sentry is not summoned
