You need Illuminati Gobtwine for gear, Illuminati Gobcoat for accessories and Illuminati Gobdip for weapons. All of these can be acquired via raiding inside of Alexander Savage.

Recently, Void Ark was updated to drop a Mhachi Farthing once per week upon completion. This can be traded for a Gobtwine or Gobcoat.

Gobdip is still exclusive to Alexander Savage, so getting a weapon above i200 requires either raiding, Thordan Extreme, or completing an Anima Weapon.
