If you’re grinding levels and hunting arcanas, the Quartero’s Curios end date is the deadline that decides whether you finish that pass or leave rewards on the table. The sources we have point to November 5 as the final day of the event, based on a GosuGamers post published on that date calling it “the FINAL DAY of Quartero’s Curios.” Below, we break down what’s confirmed, what isn’t, and how to spend your final hours smartly.
When Does Quartero’s Curios End?
Based on the source material available to us:
| Detail | What The Sources Say |
|---|---|
| Final day | November 5 (per GosuGamers’ “final day” post) |
| Year of end date | Not stated in the sources we have |
| Exact shutdown time (UTC) | Not confirmed in the sources |
| Official Valve announcement URL | Not present in the sources we reviewed |
The honest boundary: the community posts we pulled from confirm the day (November 5) and confirm the event is ending, but they do not spell out an exact hour or link back to a Valve blog post naming the timestamp. If you’re logging in on the last day, treat the event as ending sometime that day and don’t wait until the final minutes.
Why The Date Matters More Than Usual
Quartero’s Curios is a limited-time reward track where progress, unopened curios, and any arcana pulls are all tied to the event window. When the timer hits zero:
- Unfinished levels lock. You can’t grind more progress after the deadline.
- Unopened curios typically stay in your inventory as event items — but new drops stop.
- Arcanas already unlocked are yours to keep, per how Valve has handled similar events historically.
That last point is why the GosuGamers post asks the community two very specific questions: “Which level have you reached?” and “Did you get any arcanas?” Those are the two things that actually matter when the clock runs out.
A Reddit Thread Referenced March 5 — Here’s Why That Doesn’t Change The End Date
One of the community threads in our sources is titled “Today is March 5th and Quartero’s Curios is due to end.” That looks like a contradiction with the November 5 final-day post, but it isn’t necessarily one — the two posts are from different points in the event’s lifecycle, and Valve is well known for extending live events past their originally scheduled end.
What this tells us:
- The event was originally slated to end earlier in the year.
- It was extended — a pattern anyone who has followed Valve’s Dota 2 patch cycle will recognize.
- The later-dated source (November 5) is the one to trust for the actual final day.
If Valve pushes the deadline again after this article is published, we’ll update this page.
What To Do Before Quartero’s Curios Ends
If you’re reading this with time still on the clock, prioritize in this order:
- Open every curio you own. They’re worthless after the event closes if the drop mechanics get sunset.
- Finish the next reward tier, not the one after that. Guaranteed rewards beat aspirational ones.
- Play your best hero, not the meta hero. Event XP usually comes from wins and completed games, so pick what wins you games — not what the Dota 2 conduct summary tells you is trending.
- Check the in-client timer, not third-party trackers. The Dota 2 client shows the authoritative countdown.
What Patch Follows Quartero’s Curios?
The Reddit thread in our sources explicitly asks: “What kind of patch do you think will follow?” That question is on every serious player’s mind because Valve typically ships a substantial gameplay patch after a monetization event wraps — it’s how they reset the ladder and refocus attention on core Dota.
What the sources confirm: the community expects a patch. What they do not confirm: the patch number, its release date, or its contents. We are not going to invent one.
Historically, post-event patches have included:
- Hero rebalances (buffs to underused picks, nerfs to dominant ones)
- Item reworks
- Map tweaks
- Occasionally, a new hero — though these are usually telegraphed well in advance by IceFrog and the balance team
For a sense of how wild post-event balance shifts can feel when everything gets thrown at the wall, the community’s Dota Imba mode history is a fun reference — but the real patch will be more measured.
The Bottom Line
Here’s where things stand right now:
- Quartero’s Curios ends on November 5, per the GosuGamers “final day” post.
- The exact shutdown time and year are not stated in the sources we have — check the in-client timer for the authoritative countdown.
- A follow-up gameplay patch is widely expected but has not been announced in the sources we reviewed.
Open questions we’re tracking:
- Will Valve extend the deadline again, as they did earlier in the event?
- What does the follow-up patch actually change?
- Do unopened curios convert, expire, or stay usable after the deadline?
We’ll update this page as Valve publishes official information.
Wrap Up
The Quartero’s Curios end date is November 5 based on the sources available, and the smart move is to finish your levels and open your curios well before the final hours.
