The Ace of Clubs

The Ace of Clubs is a legendary sword that has been buried inside the Repliseparation Battery of the Generation Temple for hundreds of years. It has 3 forms: Daylight Form (where the blade radiates golden light and is more effective at night), Moonlight Form (where the blade has a translucent-black-and-starry aura and is more effective during day) and Twilight Form (where the blade is steel-grey, occasionally shoots off golden sparks and is double as effective as a normal sword at any time). For every day it spends inside the Repliseparation Battery, it gains 16 swords' worth of durability.
