Minecraft: Venus Sky Trap - Form and function in harmony.

This is my new mob trap design. Low tech, minimal resources with 100% loot efficiency.

I set myself the task to design and build a mob trap which delivers mobs at full health so they can be separated using mob health with 100% accuracy.

The trap can be used for an XP farm and can also spawn and separate spiders.

EDIT: It's actually a 2x2 "exit hole", the 3x2 was another design I tested.
