The Void Wyvern

The Void Wyvern is a superboss, and the final boss in the current version of the Ultraconyx Mod, which is summoned using Void energy generator. Beating it will allow you to craft the Dev Weapons. The Void Wyvern has 7,500,000 HP in Normal Mode, 11,250,000 HP in expert mode and 11,250,000 HP in Chaos Mode. It's head deals an average of 120 Dmg, the void orbs deal an average of 250 Dmg, The Guardians of the Ancient Flame and Ancient Light deal an average of 120 Dmg.

* (Note that all averages were tested on Chaos mode. ) When The Void Wyvern is defeated, The Guardian of the Ancient Abyss does spawn. There are three attack patterns for it: the first are large void orbs spawning, and then exploding in four directions but it is faster this time. Another attack are random void orbs going to a center, then going out a bit more and finnaly, disappearing. The third attack is void orbs spawning randomly in large lines coming from all directions and this one can get you in a box of death quite easily

Phase 1
The Void Wyvern has 3 phases. The first phase, there are The Guardians of the Ancient Flame and Ancient Light, that need to be killed to damage The Void Wyvern, 2 of each should spawn in chaos mode and 1 of each in normal mode and expert mode. Large void orbs will also appear and explode, sending smaller void orbs in all four directions, while The Void Wyvern trys to ram in to you.

Phase 2
Phase 2 starts when the Void Wyvern's HP reaches 1/10 of it's max health, it's sprite will start changing colors and it will move much faster and is hard to hit. Also, the void orbs will stop spawning.
