I will make you a weapon of your choice and give it one ability that you want.

Give me one called timer. It can slow down time for the world around me for a short period of time

Bloodscythe
Sword that can absorb enemies health then make them undead allies

a sword that looks like a very big electric guitar
the shredsaber

Ooo
This is a tough one
Gimme a weapon that can transform in Every. Other. Type of weapon. And name it Zungaarfus

Give me one called Fluffy Bunny (Based off of a demotivational I saw on Reddit earlier). Its enchantments are twofold: if slain by Fluffy Bunny, the enemy's ghost is not permitted to go to the afterlife because m a g i c, and has to float around the material world, and can only talk about the embarrassment of being slain by a sword called "Fluffy Bunny." The second enchantment: if an enemy survives an encounter with Fluffy Bunny's wielder, they are instantly forced to surrender to said wielder from that point on.
