The Lunar Flare is an endgame mage weapon that drops from the Moon Lord. Similar to the Blizzard Staff, it rains down on enemies, except that this spell can pass through blocks, depending on where it is used. It can quickly kill most enemies with its high base damage.
It summons three projectiles that appear as turquoise streaks, and create a small explosion on impact.
The projectiles will pass through any blocks above the cursor, making it a much more viable option for combat in caves and in the Dungeon than similar projectile-summoning magic weapons.
