During this event, any player who enables Mayhem Mode will have an increased drop rate for Anointed Gear, along with extra XP for defeating enemies, and reduced values for various Mayhem Mode penalty modifiers.Mayhem Mode is unlocked by finishing the main story for Borderlands 3, so these rewards will be locked to you if you haven’t finished the main campaign yet.On the other hand, the Twitch-related ECHOcast rewards will be available to anyone who links their Shift account with their Twitch Account. Viewers and streamers on Twitch will find more frequent Badass Viewer Events (a permanent change) and accelerated voting periods to make viewer-controlled badasses more difficult. Rare Chest Events will also have a 100% guaranteed win rate, instead of just one-in-four.Gearbox has a blog on how to link your Shift and Twitch accounts here . Even if you just watch Borderlands 3 on Twitch without owning a copy, any rewards you earn through Rare Chest Events are yours if you link your account. The rewards will wait for you in the in-game mailbox if you ever decide to pick up a copy.The update goes live later today and lasts until October 29 when the final event begins.

Borderlands 3's 10-year anniversary event is on week 3. This week's theme: "Show Me the Eridium!"During this week, standard enemies will now drop Eridium, Eridium drops from Mayhem Mode will increase, and Moxxi's Vault Line slot machine will cost less Eridium to play. Furthermore, cosmetic items and Anointed weapons at Crazy Earl's hideout will be discounted.Players will need an Eridium Resonator to break Eridium deposits and collect shards, but luckily the Resonator is an item players will naturally pick up over the course of the main story campaign. The Resonator is obtained during the Eden-6 questline.The "Show Me the Eridium" event will be available starting at 3 pm PT/6 pm ET tomorrow, Tuesday, October 15. The event will last until October 22, at which point Borderlands 3 will begin spinning up next week's event, "Mayhem on Twitch!"
