The full Safi'jiiva Siege won't actually be going live until Friday, 13th December in Monster Hunter World: Iceborne, but we've got an early look at armour stats for the monster's set.
The video below shows off the beta version of the Safi'jiiva armour. You'll be able to earn this by slaying the Safi'jiiva from this Friday, in the Siege mission which lets up to 16 players fight the beast at once.
There are two versions of the main armour skill: Dragonvein Awakening, unlocked with three pieces of the set equipped, and True Dragonvein Awakening, unlocked if you're wearing all five pieces.
