End spike

Obsidian pillars (also known as obsidian spikes or obsidian towers) are generated structures in the End that are made of obsidian.

Generation
Obsidian pillars generate naturally in the End.

Structure
Obsidian pillars are composed of obsidian, with a single bedrock block and an ender crystal on top of each pillar (although, due to, the crystal will immediately destroy the bedrock block). They have circular forms.

The pillars generate in the end with heights at y=76, 79, 82, 85, 88, 91, 94, 97, 100, and 103. 10 Pillars are arranged in a circle in a random order. Second and third shortest pillars have iron bars around their ender crystal.

In the Console Edition, the ender crystals on the two tallest obsidian pillars are surrounded by iron bars.
