The old Duel Arena is no longer the place to buy things in OSRS; it was replaced by the PvP Arena, and the reward shop there is run by Mubariz near the entrance to the Emir’s Arena.

Where to buy stuff

  • PvP Arena rewards shop : This is the main in-game shop tied to the old Duel Arena area now.
  • Shop of Distaste / nearby Al Kharid area : Some guides and item databases still list legacy Duel Arena-related shops and vendors in that area.
  • Grand Exchange : For regular trading and buying items from other players, this is usually the main place.

What changed

The classic Duel Arena was removed, and the area now centers on the PvP Arena/Emir’s Arena system instead.

Practical note

If you meant “where do I buy items around the Duel Arena area,” the safest answer is the PvP Arena reward shop or the Grand Exchange , depending on whether you want arena rewards or normal market items.

TL;DR: The Duel Arena itself is gone, and buying now usually means the PvP Arena reward shop near Emir’s Arena or the Grand Exchange.
