Water Bolt

 is a magic spell found in the Dungeons of Terraria, hidden amongst the numerous books on the shelves within. When cast, it releases a blue, ricocheting projectile which looks very similar to the spells used by Dark Casters. Similar to the Flower of Fire, the bolt will bounce up to five times off of solid objects, or until it hits an enemy; whichever happens first. Unlike the Flower of Fire, however, Water Bolts are not affected by gravity, and will travel in straight lines until it dissipates or hits a target. Water Bolt is somewhat inferior to the Flower of Fire, in that it's slower, does less damage, and costs more Mana to use. However, aiming a straight-moving Water Bolt is somewhat easier than predicting the arc of a bouncing ball of fire.

To get this item, a player must use a hammer to knock books loose from the shelves inside a Dungeon, as there is a chance Water Bolt will be hidden amongst them. Water Bolt cannot be crafted, does not appear in Chests, and does not drop as loot from enemies.
