Flak Kraken - Official Calamity Mod Wiki

The Flak Kraken is a unique craftable Hardmode ranged weapon. It summons a yellow reticle at the cursor's location that deals constant damage to any enemy within it, piercing infinitely. The reticle also inflicts Crush Depth debuff. Similarly to other weapons such as the Phantasm, the Flak Kraken will "spin up" the longer the fire button is held, increasing its damage per second and area of effect.
