This season 7 week 1 epic quest requires you to upgrade 3 weapons at weapon upgrade benches

Season 7 brings back weapon upgrade benches that are scattered around the map. When you use a weapons upgrade bench you will be able to buy upgrades with your gold bars.

You can collect gold bars in similar ways you did in season 6. You can accept and complete quests from NPCs, eliminate players and find them in chests. There are also payphones that offer quests as well as NPCs.

Upgrading a weapon costs a minimum of 200 gold bars for a common weapon. It goes up by 100 gold bars for each tier of rarity above that. So uncommon to rare is 300 gold bars and rare to epic is 400 gold bars.

See the map below for locations of weapons upgrade stations.
