Golden Shower

The Golden Shower is a Hardmode magic weapon that fires an arching piercing golden stream, similar to the Aqua Scepter. The Golden Shower fires three times per click, each stream can pierce up to four enemies, and the player can change the direction of aim between these sprays. Enemies hit will be inflicted with the Ichor debuff, which lowers their defense by 20 and causes them to glow gold, even in complete darkness. However, this cannot be used to explore the map, as the enemy coated in ichor does not actually emit light.

Crafting the Golden Shower requires ingredients found only in worlds containing Crimson, so it cannot be obtained in worlds containing Corruption without ingredients from other worlds. This is no longer true as of 1.4, as you can now purchase Crimson Seeds from the Dryad while in a Graveyard in a Hardmode Corrupt world.

However, an alternative modifier is Manic, for those who just want to benefit from the Ichor debuff this weapon applies.

Tips

 * The Golden Shower's fast speed and piercing ability make it a great item for fighting large groups of enemies (e.g. events).
 * Its ability to reduce defenses makes it effective against bosses, as one can attack with it and then equip a stronger weapon to deal even more damage. Alternatively, one can use Flask of Ichor, Ichor Bullets, Ichor Arrows, or the Bladetongue, though the Golden Shower retains the advantage of not using any resources.
 * It is one of the best magic weapons for taking out worm-type enemies before obtaining a Magical Harp.
 * The Ichor debuff vastly improves the DPS of weapons that deal many hits per second, such as the Crystal Storm, Cursed Flames, or the Magnet Sphere.
 * Enemies hit by the stream will glow even in complete darkness, and the glow is bright enough to match that of a Hunter Potion.
 * It is one of very few weapons acquired in early Hardmode (or in the game at all) that remains valuable at the end of the game. Although its damage will be very minor, it will still inflict its debuff (which few are immune to), making it especially useful for boss fights, end-game enemies, and increasing your DPS.
 * Since it is easily obtained early on in Hardmode, and is very useful for surviving the increased difficulty, obtaining it should be a priority as soon as the Wall of Flesh is defeated in Crimson worlds.
 * Even though the Destroyer is immune to the Ichor debuff, the Golden Shower is effective against it because it can damage many segments at once.
 * If used along with the Betsy's Wrath, the player can remove 60 defense from enemies, allowing for even more damage.

Trivia

 * It is the Crimson counterpart to the Corruption's Cursed Flames, since it is crafted from a Spell Tome and unique ingredients that drop from a few of the Underground Crimson's enemies.
 * In, approached  in the form of golden showers, a union from which she begat the legendary hero.
 * "Golden shower" is a slang term for, a sexual fetish. The name in Terraria is likely referring to the fact that the attack resembles a stream of urine.
