Melee weapons range from "useless" to "I AM GOD!"
I crafted myself one of the Developer Crafts weapons. Can you guess from the name which category it belongs in? Here's a hint: It's a knife that kills normal enemies in a single, instant hit 100% of the time that synergies extremely well with the throwing character's AoE skill.

Oh yeah, and I can craft more at any time using only a battery, five diamonds, and 10,000 dollars.
