Here's my design for the Star Wars keyblade. I think it's awesome because it resembles the Kingdom Key. 

It's passive ability is "Death Boost."

In the final Fantasy Series, Death is a spell that can instantly kill any enemy. I would want this to be an ability you can equip in KH, that has a 1% chance of being unleased per hit. However, thiis keychain would increase the ability to 5%. But I don't know if that's too powerful. What do you think?

what about the key-shaped edge at the end?almost every keyblade has one and the hilt is kinda an off me.

Pretty cool but still no Star Wars please.

Who needs a Death Star when you've got a Keyblade!

I like it! but it needs the key-shaped edge

Absolutely not. Can you imagine how easy boss battles would be if roughly 1/100 hits would insta-kill an enemy? I'm sure they have thought of this, but it just doesn't fit in KH.

The blade is too simple but good job

Then possibly something even less. 0.1% would work, actually. Maybe bosses are immune to the ability.
