Deep dark Loot: Soul Blade-Ward off the Warden

One cool deep dark loot item could be the Soul Blade. The Soul Blade is a knife with a blue aura that can be found in the chests.

The blade does no knockback, very little damage, and is close range but can be swung at incredible speed and causes no armor damage. It can be charged up to make a very heafty swipe but it must be charged up to its max, so basically its all or nothing. Killing any mob with a soul with the blade will cause it to drop it's max xp and a cool little soul particle.

The Warden can be warded off with a strong swing from the Soul Blade. You won't be able to hurt the Warden for a while but the Warden will let out a painfull screech and be stunned for about 5 seconds, being unable to move or sense vibrations. In the mean time, the blade will be disabled until renabled at an anvil.

I think this item has a lot of potential and a close range, last resort defense from the warden is definitely a cool gameplay mechanic.
