We have made a change to VIP Chests to remove Traitstones from their core drop pool. This means that VIP Chests will always give either 2 Epic Troops, 1 Legendary Troop or 1 Mythic Troop.
Players will still have a chance to earn Traitstones, as VIP Chests will have a 30% chance per key to earn 2 bonus Arcane or Celestial Traitstones (Traitstone rewards are the same as what was available in VIP Chests in the previous version).
