I'm thinking that there should be a sword called "Vanishing Blade" that when you attack makes you warp behind the monsters and is 1 powerful hit that has high probability of stunning or freezing the monsters. Basically, when you focus on one opponent you'll keep teleporting after every one hit allowing you to teleport between three enemies if need be. The CHARGED attack would be a vanishing attack, which makes three clones, which does a chain attack, meaning the first clone would hit and stun, the second will hit 1.5 seconds later, and the third will hit 2 seconds later stunning it again.

Secondly, there should be a gun called the "Banisher" which same as the blade, it shoots 2 powerful shots behind enemies which could stun or freeze. The ultimate charge attack would allow you to attack regularly behind an enemy, but with 6 shots.

Lastly, I propose a bomb called "Uno Segundo" because it is gonna take only one second to charge and when you throw it, it will pop up behind and explode the instant behind a monster causing perhaps stun or freeze damage.

So what do you guys think? If you like it please support it.
