This checklist is current as of now, but some details may change. We’ll keep monitoring for updates and adjust if anything changes.
Many achievements are rewards will be removed when Patch 11.2 drops next week and when Season 3 starts the week after. Therefore, we’ve provided a list of all the stuff you should focus on during the final moments of the season!
What to Do Before Patch 11.2 Goes Live
Here are the activities you may want to complete for rewards before August 5.
The War Within Season 2 Meta-Achievements
The following meta achievements will be gone when Season 2 ends:
The War Within Season 2: Master Blaster: Accomplish one of the following feats during War Within Season 2 on your current character: - Obtain 1,600+ PvP Rating

Elite: The War Within Season 2: Earn the rank of Elite during The War Within season 2. Rewards the seasonal character title, “the Elite.”
Turbulent Timeways
The Turbulent Timeways event concludes on August 5, which means you won’t be able to get the 
Chrono Corsair for a while. But don’t worry, Blizzard always adds mounts from previous Turbulent Timeways events to Timewalking vendors. Just make sure to save up at least 5,000 Timewarped Badges to buy it in the future!
Level Up Your Characters!
The Winds of Mysterious Fortune ends on August 12. The event increases XP and reputation gains by up to 105% on live servers. Now’s the ideal time to level up your alts or your new main!
Get the OC91 Chariot Mount
Right now, getting 
OC91 Chariot from Overcharged Delves is extremely easy. All you have to do is max out all the talents available in the Overcharged Titan Console by collecting and spending Titan Discs. This is easily doable by spamming Tier 1 Overcharged Delves.
When Season 3 drops, Undercoins will reset, and the mount will be available on Sir Finley Mrrgglton for 15,000 Undercoins! Get it now while it’s so easy to get!
Puzzling Cartel Chips
The Puzzling Cartel Chips vendor will be removed from the game when Season 2 ends, so don’t forget to spend your last chips on gear while you still can!
PvP Season 2 Elite Sets
PvP Season 2 Elite appearances will no longer be earnable once Season 2 ends.
What to Do Before Season 3 Starts
Here’s what’s going away with the start of Season 3 on August 12.
Spend Your Undercoins!
Undercoins will reset to 0 when the new season starts. Therefore, don’t forget to spend them on cosmetics, or turn them into gold. You will find more details here.
Season 2 Raid Rewards
Here are the achievements tied to the Liberation of Undermine raid that will be gone when the new raid opens:
- Ahead of the Curve: Chrome King Gallywix – Defeat Chrome King Gallywix on Heroic difficulty or higher before the release of the next raid tier.
