Water Bolt

Dungeon bookshelf discovery and ricocheting hydro orbs

Discovered on Dungeon bookshelves by mining books that display a blue cover wrapped with a golden ribbon. Casting costs 10 mana, launching a slow-moving sphere of water that deals 19 magic damage with 5 knockback. The bolt pierces up to 5 enemies and bounces off solid blocks, lingering in flight for several seconds while casting faint illumination across dark passages.

Enclosed boss arenas and early magical dominance

Water Bolt provides strong utility in narrow corridors and constructed arenas. Creating a boxed battlefield with solid blocks turns each cast into a dense field of ricocheting projectiles, tearing through Eater of Worlds segments or stunlocking the Wall of Flesh along the underworld bridge. It remains competitive well into early Hardmode before being superseded by Crystal Storm. Its best modifier is Mythical.

Trivia

• Water Bolt books only generate below the surface layer, preventing players from looting them before defeating Skeletron.
• Each water projectile can bounce off solid surfaces up to eight times or pierce five distinct targets before dissipating.
