Challenge Rules: Kobold Island - The Disruptor

Quick Start Guide

  1. Help activate and defend Extractor machines so they can harvest as many Dragonshards as possible from a monster filled island!
  2. Retrieve the stolen mechanical parts needed to repair Extractors by killing kobolds!
  3. Thwart a Giant Skeleton who can periodically disrupt all of your Extractors!

The Rules

The Extractors

  • Dragonshard Extractors on the island will extract Dragonshards - activate and upgrade as many Extractors as possible to maximize your Dragonshard extraction rate!
  • Extract as many Dragonshards as possible before time runs out.
  • Once you activate an Extractor, you’ll need to protect the active Extractor from the attacks of various roaming monsters.
    • Tip: You can earn extra treasure for killing red named boss monsters!
  • If the monsters do enough damage to an Extractor it will shut down and need to be activated again, costing you more resources.
  • Watch out for the Disruptor, a powerful giant skeleton that will appear at random. The Disruptor will stop all Extractor production until he has been defeated.

Activating Extractors

  • Extractors must be activated before they begin to extract Dragonshards. Click on the lever in front of the Extractor to see the activation options.
  • You will need Mechanical Parts to activate Extractors. You get Mechanical Parts by killing the kobolds that infest the island.
    • Tip: Non-kobold monsters never drop mechanical parts.
  • Camps of Kobolds can be found scattered across the island. Hunt down the kobolds to retrieve the mechanical parts needed for the Extractors.
    • Tip: Desecrating a Kobold Idol will drive all the kobolds away from that camp forever, but also give you several Mechanical Parts right away.

Upgrading Extractors

  • Extractors can be upgraded using a combination of Dragonshards and mechanical parts taken from the kobolds. Upgrading an Extractor makes it extract faster, and allows it to take more damage before it is deactivated by monsters.
    • Small Extractors can be upgraded to Level 2.
    • Large Extractors can be upgraded to Level 3.
    • Tip: Remember that spending Dragonshards subtracts from your quota.

Purchases from Extractors

  • You can buy Magefire Cannons from all Extractors, and you can buy temporary Shrines from Large Extractors.
  • You can place Magefire Cannons to protect the Extractors. Magefire Cannons can also be upgraded using Dragonshards and mechanical parts.

The Archon

  • A benevolent Lantern Archon will sometimes appear and drop Dragonshards that you can collect and use to add to your score.

Supply Crates

  • From time to time a patrolling airship will drop supply crates. These crates contain orbs that will temporarily enhance your abilities in various ways.
  • Supply crates will only remain for a limited time!
