Firebourne

What is the Firebourne?
The firebourne is an end-game boss in Kobolds Never Die. The Firebourne has a reasonable difficult summoning procedure, is challenging and can only be killed by magical damage. For beginners, you may wish to try this by yourself, with no enemy team to familiarize yourself with the spawning and killing of Firebourne.

By yourself you can reliably summon and kill Firebourne in ~25 minutes (times varying depending on equipment) and in a 4v4+ match Firebourne is an excellent method of attaining powerful equipment to give your team an advantage, be warned though, the enemy team(s) will be made aware of your spawning of the Firebourne.

How to summon the Firebourne
You will need to attain the 5 brimming items, then take these items and stand in the middle of the crater at top right section of the map.

The brimming items are invisible to the naked eye, you'll require Sage Mode or Clairvoyance (or any other form of detection) to see them. Be hasty, if you don't pick it up within 60 seconds the brimming items will vanish! Next bring the required items into the crater and the Firebourne will spawn.
 * 1) You'll need the Brimming Tome, which is most easily obtained by killing the Raging Arcane Beast. Use clairvoyance and look among the other loot, you'll find the Brimming Tome. Also the Brimming Tome drops from the Wounded Wizard quest once you heal up and drops his loot.
 * 2) Brimming Heart are both obtained by killing the helpless mammoth at the bottom left corner of the map. If it's dead already, no worry, wait 5 minutes and it will return.
 * 3) Brimming Essence is obtained by eating a Water Scorpion while standing next to a campfire. Use detection of some kind and you'll find it nearby.
 * 4) Brimming Soul is obtained by using the Cursed Druid Scepter's active on an elder tree. The brimming soul will be nearby the elder tree.
 * 5) Brimming Shard is dropped when a gold node is completely mined out.

I recommend Lunar Seer's Nirvana and Demonward as excellent items of protection and offense against the Firebourne.
