this Arknights best teams breakdown only covers the three-day stretch. Part 2 of Yesterday's Sea closes at 03:59 on October 23; the salvage plan hands out the five-star operator Lugo and a furniture set. The 04:00 update on October 22 rotates the permanent banner and the advanced certificate shop. The Thanks Celebration stream at 19:30 on October 24 is the first place the new limited banner will be described. Below: a pull budget in Orundum, which resource stage to farm, and three account states that decide whether you pull today.
Applicable version: as of the 2026-10-16 update (no version-number system; 2026-10-16 16:00 was the latest hotfix)
Arknights Thanks Celebration stream: what October 24 at 19:30 actually delivers
Producer Letter #70 states that the 2026 Thanks Celebration preview stream runs at 19:30 on October 24, covering celebration events, a new SideStory, a new limited headhunting banner and the following version plan . It is the only information source this week that can change how you spend.
Three blocks of information, one of them decides your pulls
The stream covers schedules, the new SideStory, and the limited banner. The first two change what you farm; the third changes whether you save. The letter also carried a reward of 200 Orundum plus 5 Polyester Group, delivered from 17:00 on October 17 with a seven-day mail expiry . Those 200 Orundum expire around October 24 if you never claim them — the single easiest thing to lose this week.
Claim the letter reward first
Seven days from 17:00 on October 17 puts the deadline near 17:00 on October 24. The amount is small, roughly one pull, but the pattern is "skip it and it is gone, claim it and you gain nothing extra" — one tap at login.
Do not extrapolate banner numbers
The limited banner composition, rates and pity rules for the Thanks Celebration have not been published. This guide does not estimate them. Community rumours are not a basis for spending; wait for the stream and the official notice that follows it .
Arknights Yesterday's Sea part 2: the last night that matters
Yesterday's Sea runs from 12:00 on October 9 to 03:59 on October 30, unlocked by clearing main story 1-10 . It shipped in two parts: "Rea-Iberia" opened at 12:00 on October 9, "Our Iberia" at 16:00 on October 16, and both close at 03:59 on October 23.
Why part 2 outranks farming
Part 2 has a one-week window; after October 24 first-clear rewards are simply gone. Farm stages stay forever. The trade-off is straightforward: irreversible progress first, repeatable output second. At 240 sanity per day a week yields about 1,680 sanity , and half of that is enough for a full part 2 clear.
What the salvage plan pays
The event's salvage plan converts stage progress into rewards, and the notice names the five-star event operator Lugo plus the Harbour Club Reception Room furniture set as the main prizes . Furniture is one-off, operators join teams — push progress first, then come back for three-star conditions.
Arknights October 22 banner and certificate shop: should you spend Orundum
Short answer: no. The 04:00 update on October 22 refreshes the permanent standard headhunting banner and rotates the advanced certificate shop to Nief and Bobb . Neither is a reason to spend today.
Three account states, three decisions
Under 5,000 Orundum and no reliable ranged core: pulling to the first six-star is defensible, but two days of patience costs nothing in probability. Between 5,000 and 12,000 with a mostly complete roster: exchange in the certificate shop only, leave headhunting alone, bank the Orundum for the limited banner. Above 20,000: both are affordable, yet the limited banner still wins because limited operators never enter the permanent pool.
Opportunity cost in one sentence
Permanent operators return in future rotations and certificate shops; limited operators return only on rerun, often a year later. That single asymmetry is the entire argument for holding this week .
Arknights resource budget before the Thanks Celebration
Only three resources matter: Orundum, Originite Prime, and sanity. Counting weekly keeps the numbers comparable with your own stock.
Weekly Orundum and Originite
Daily and weekly missions together yield roughly 1,200 Orundum per week , and this week adds about 200 from event shops and the letter reward. Originite from first clears runs 3 to 5 per week at a normal pace. Combined, that is three to four pulls a week; if you are more than 30 pulls from pity, saving cannot close the gap in time, which argues even harder for waiting for the limited banner instead of topping up a permanent one.
Splitting 1,680 sanity
240 per day, 1,680 per week . Split it three ways: about 600 for the part 2 first clear, zero for the Hengyuan Jinliang login track, and the remaining 1,000 for event shop exchanges and Integrated Strategies. Content Expansion I of the Integrated Strategies theme "Sunken Black Flow Sea" is already live ; it consumes time rather than sanity and fits after the first clear.
Arknights Hengyuan Jinliang and farm stages: what to run this week
Hengyuan Jinliang opened on October 11 as a crossover event . Its rewards are login-based and shop-based, not combat-based.
Is the Hengyuan Jinliang login still achievable?
Yes. Progress counts cumulative days, and three days unlock the Plush Reading Companion furniture set and similar rewards . The daily cap is one claim per day; there is no sanity cost and no requirement beyond logging in, so three days from today still finishes the track.
Event shop or permanent farm stage
Event shops usually beat permanent material stages on exchange efficiency, and this event closes at 03:59 on October 30 . So the order is: exchange what the event shop offers, then farm the permanent stages for the rest. This is not "events are always cheaper" but "events expire and permanent stages do not" — time is the actual constraint.

Game Guides
- Palworld 1.0.5 Gathering Chain After Ancient Bark Went Level 1
Version 1.0.4 dropped the Work Suitability requirement for harvesting Ancient Bark to Lv. 1, and that one change rewrites early base staffing: you no longer breed a dedicated high-Lumbering Pal just to fell trees, because any Pal with Lumbering can now do it. Patch 1.0.5 (2026-09-15) only fixed texture loading and did not touch the rule, so the conclusion stands.
- Reverse: 1999 4.0 Free Pulls and the Guaranteed-New Six-Star: Order and Use
Version 4.0 hands out free pulls in three places: the guaranteed-new six-star login reward, a 40-pull check-in track, and, on the global client, a promotion advertised as up to 100 free pulls with 14 on login (CN client 4.0.0, global 3.8). The thing most players waste is not the pulls themselves but the guaranteed-new six-star, spent on an attribute they already cover. Count the gaps first, then claim.
- Love and Deepspace 6.0 Free Resources: Which Four-Star Memory and What to Exchange
Version 6.0 hands out five things that cost nothing: a free four-star Memory selection, Wish Tickets, Diamonds, curated outfits, and photo backgrounds plus poses, with the official notes stating that home-related play yields more than 6,000 Diamonds in total. The order that works is: decide the selection first, spend Diamonds second, and treat the returning limited pool as the last item on the list.
- Honkai: Star Rail 4.6 Wrap-Up: Three Days Left on Planar Fission and the Currency War Reset
Version 4.6 is on day 25 and three countdowns are running at once: Planar Fission double drops end at 03:59 on October 25, Currency War Zero-Sum resets part of its rewards when 4.6 closes, and the bug-fix compensation expires at 23:59 on October 28. Doubled runs are capped and never refresh during the event, so the job for these three days is spending the remaining runs, not re-planning a farming route.
- Genshin Impact 7.1 Fortune Forecast Wrap-Up: Claim Before 09:59 on October 23
Three deadlines matter on October 22 in Genshin Impact: Fortune Forecast's results window closes at 09:59 on October 23, the Snowball Fight point cap climbs in stages to 6000, and the Skirk and Escoffier banners stay open until 14:59 on November 3. Claim the forecast rewards first, cap the snowball points second, and leave banner decisions for last.
- Wuthering Waves 3.7.2 Free-to-Play 30-Day Route: Skills Before Echoes
For a free-to-play account, the only order that matters in 3.7.2 is this: week one pushes your main DPS skill levels and weapon, week two closes the echo set at 4+3+3+1+1, week three starts running Tower of Adversity with two teams, week four polishes substats. Five echo slots cap at 12 total COST, so a broken build is a configuration error, not bad luck.
- Zenless Zone Zero 3.3 Bizarre House Event: Calendar and Phoenix Pull Advice
Bizarre House Haunting opens at 10:00 on October 22 for Inter-Knot level 20 and above, while version 3.3 itself runs until 06:00 on December 2 — 42 days in total. Lock in the free pulls first: ten Encrypted Master Tapes from the seven-day login track and ten Boopon from the November login track, then decide whether Phoenix or Severian deserves your Polychrome.
- Palworld 1.0.5 Popularity Poll and Side by Side: Fix the Base First
The official October 20 announcement put Sekhmet first, Solenne second and Chillet third on the Pal poll, with Zoe, Auri and Saya topping the character poll, and named the next update Palworld: Side by Side for winter 2026, so the useful work before then is rebuilding your base lines around the Ancient Bark change to Lv.1.
