The True Copper Shortsword is a HardmodeShortsword that has an immense damage stat, but a slow use time. It launches a rainbow projectile that causes a debuff similar to the On Fire! debuff for 10 seconds.
This weapon is considered as a joke weapon, based on the fact that the Copper Shortsword is one of the the weakest weapons in Vanilla.
Comedically, it is also the most iconic weapon in Ancients Awakened, and is featured in the mod's icon.
The projectile is able to hit enemies before the sword can, due to it being launched at the start of the animation.
The debuff is not the On Fire! debuff because it deals 25 damage instead of 1, is not extinguished by water, and causes a quick series of 1 damage just before extinguishing.
