Each ticket has its own use. "Golden tickets" are Fellowship Tickets that can only be used in the Pact of Fellowship (for characters) or Companions of Fellowship (for companions). "Silver tickets" are Metal Tickets that can only be used in the Arena's Metal Zones. The only tickets that can be used during the Companions of Truth events are the blue Companion Tickets. You must have 10 of these to do a 10-pull to benefit from this event.
