Death Sickle

Dropped by Reapers during a Solar Eclipse event. The 'deathly sickle' has a fair range, passes through blocks, does a slight knock back and leaves a fair amount of light. Excellent for mining and fighting as the 'sickles' hover for a second or two when they reach maximum range.

Trivia

 * It isn't a Sickle at all, it's actually a Scythe.
