I checked on Antica no one is selling and we are days into the Tibia Anniversary and I've killed Lord Retro multiple times without obtaining the Brass Button or Decorative Plume. These items don't disappear when used and are used for obtaining the Formal outfit from the event. I'm curious to know what are the chances to loot both these addon items? Is it very rare? Has anyone looted it yet that you know of? I've spoken to multiple friends of all levels and had no success.
