Polarities Mod/Celestial Storm

The Celestial Storm is a Hardmode, post-Lunatic Cultist atlatl crafted using Vortex Fragments. When swung, it launches a portal resembling the ones created by the Lunar Portal Staff, which will gravitate towards the player and attempt to orbit around them for a short time before disappearing. They will fire darts towards the cursor at regular intervals, able to launch up to three per portal before disappearing; despite this, each portal only costs one dart to launch, effectively tripling your ammo's effectiveness. While the portals themselves can pass through tiles, their fired darts behave as normal, thus reducing the weapon's damage output when used next to a flat surface as the darts will collide with the terrain immediately after being fired.

Trivia
