Dungeon gear

If you complete a dungeon in explorable mode you will receive 60x tokens from that dungeon. These tokens can be used to purchase armor, weapons and runes as well as some other items.

If you want the gear from Ex AC. You will be able to start collection tokens for that gear at lvl 35.

The cost of every item differs and the vendors can be found in Lions Arch near the WvWvW portals.
