Genshin Impact 7.1 anniversary maths: the free 20 pulls, where both invitations land, and the real cost
Genshin Impact 7.1 anniversary, as arithmetic. How the sign-in and mail convert to 20 pulls, what each invitation is worth in pulls saved, whether the build cost belongs in the total, and three cases where spending it loses.
Genshin Impact 7.1 anniversary: laying the accounts out
What the anniversary hands out splits into three kinds: plain currency, sign-in items, and invitations. Each converts differently, and mixing them up is how people get the total wrong.
Kind one: things that convert straight into pulls
Primogems in the mail and Intertwined Fate from the sign-in sit here. Primogems convert at 160 per pull; one Intertwined Fate counts as one pull.
Kind two: things that convert into resources, not pulls
Materials like Sanctifying Essence don't belong in the pull maths. Treat them as resin you didn't have to spend.
Kind three: invitations, which cost zero pulls
"Through Snowy Lands, Forging the Edge" invites any one standard 5-star on login, and "Tabletop Troupe: Adventure's Eve" invites one limited 5-star after its quest. These convert as pulls you didn't have to spend, not pulls you gained.
Genshin Impact 7.1: how the free side adds up to 20 pulls
Two free streams, and together they're exactly 20 pulls.
The sign-in stream: 10 Intertwined Fate
"Golden Journey, Blazing Stars" gives 10 Intertwined Fate for seven days of sign-in. One Fate equals one pull, so that's 10 pulls, or 10 × 160 = 1600 Primogems.
The mail stream: 1600 Primogems
"Letters of Good Fortune" delivers 1600 Primogems across four separate letters, and 1600 ÷ 160 = 10 pulls. Note it arrives in four drops, not one, so log in a few times to collect.
The two together: 10 + 10 = 20 pulls
Twenty pulls is 20 ÷ 90 ≈ 22% of a 90-pull guarantee line. If you were already planning to pull Vasnera, that's a fifth of the way there for free.
Genshin Impact 7.1: what each invitation is worth
An invitation isn't pulls, it's a character handed over. Convert it against what you would have spent.
Standard invitation: it removes the lottery
Standard banner 5-stars arrive at random. Inviting one on login deletes the "wait for it to drop" step, so you never budget for it.
Limited invitation: it saves the guarantee
The "Tabletop Troupe: Adventure's Eve" invitation saves you the cost of reaching the guarantee line. On the in-game cycle that line is 90 pulls, so this one is worth "up to 90 pulls", not a flat 90.
Using both together
The reason the limited invitation goes to your biggest gap: the standard pool is always there to roll against, and a limited banner isn't. Spend the standard invitation on a hole in your roster, and the limited one on whoever you were going to pull anyway. When both are missing, the limited invitation goes to your biggest gap.
Genshin Impact 7.1: three cases where spending the 20 pulls loses
Once the sums are done, three kinds of player lose by using them.
Case one: pulling just to fill the archive
If the two invitations already complete your collection, pulling further only buys duplicates. Keeping the pulls is worth more.
Case two: treating the sign-in pulls as compulsory
Intertwined Fate doesn't rot, but treating it as "must spend now" pushes you into banners you never wanted. That's the most common loss.
Case three: leaving the build cost out
Pulling is only the first sum. Artifacts, talents and Mora are the second. A character you can't afford to build means the maths isn't finished.
Genshin Impact 7.1: the questions left after the sums (FAQ)
Can I claim both invitations?
A: Yes. The standard invitation is on login; the limited one needs the "Tabletop Troupe: Adventure's Eve" quest completed .
How many pulls does the anniversary give for free?
A: 20. Seven days of sign-in gives 10 Intertwined Fate (= 1600 Primogems = 10 pulls), and mail adds 1600 Primogems
Where do the 1600 Primogems come from?
A: "Letters of Good Fortune" delivers them across four letters, so they arrive in stages rather than at once .
Is Vasnera worth pulling?
A: She lets the team trigger a star Swirl reaction, which pays off only with the right partners. Without them, spend the free 20 pulls first .
Standard invitation: new character or a constellation?
A: Missing a main DPS, take the DPS slot; one constellation short of a key breakpoint, take that. If neither is missing, fill the roster gap.
Scope note: version, event and reward details come from the 7.1 official update notes (first-party). The 160-Primogem conversion and 90-pull guarantee are in-game values and are marked as such; nothing is extrapolated. Day-by-day character material lives on gghubs.com's Genshin Impact section.
Game Guides
- Palworld 1.0.5 in three tables: cakes, Work Suitability, and condensation versus technology
Just run your save against these three tables: for breeding read column one of the cake table, for your base read column three of the Work Suitability table, and start condensation at 48 Pals. You don't need to memorise any of it; pull the table up and read one row.
- Reverse: 1999 4.0 "Gate-Keeper": what I claimed first coming back, and what I nearly missed
I came back this week, and the first thing I did wasn't the story. It was claiming the five login rewards one by one. Then I noticed the limited sign-in gives 40 pulls over several days, and I'd skipped two of them. By the time I went back, the countdown was nearly done.
- Love and Deepspace 6.0 home: 20 player questions answered, and 6000 diamonds that expire
How much does the home system pay? Officially, "over 6000 diamonds". It isn't a lump sum. It's spread across cooking, handcrafts and tasks. Claim it in the wrong order and some of it expires.
- Honkai: Star Rail 4.6 "Dance With Beasts Before the Moon Rises": who should skip, and who should claim first
If your archive is full, skip this one. If you only run the story and don't care about strength, skip it. Pearl is a limited 5-star, Elation and Ice, and the whole question is one thing: are you short an Elation slot? If yes, pull. If no, keep the free pulls.
- Wuthering Waves 3.7 Hsin build retrospective: I rolled substats first, burned two rounds of Echoes, and here's where the order went wrong
If your archive is full, skip this one. If you only run the story and don't care about strength, skip it. Pearl is a limited 5-star, Elation and Ice, and the whole question is one thing: are you short an Elation slot? If yes, pull. If no, keep the free pulls.
- Zenless Zone Zero 3.2 Shiyu Defense room 3: a third DPS or a dedicated stun slot (two-column table + 3 tests)
**Zenless Zone Zero 3.2 Shiyu Defense** room 3, side by side. Damage ceiling, stun-window consistency, investment floor, and the cost of a wipe, compared row by row, plus 3 tests and 2 places to stop.
- Arknights "Yesterday's Sea" week-one timeline: 24 hours before launch to day 7, one move per day
**Arknights "Yesterday's Sea" guide**, laid out by day. Bank sanity before launch, split your 240 points on day one, buy the first two shop tiers on days 2 to 3, catch up on levels and stages on days 4 to 5, clear leftovers on days 6 to 7. Sources sit in the table at the bottom.
- Palworld v1.0.5 Boss and Tower Guide: Jetragon Tech Change, Base Defense and the World Tree Route
Palworld's endgame combat splits into three tiers: tower bosses, field bosses and the World Tree main line. v1.0.5 itself only fixed a texture-resolution loading issue, so what actually changes your approach is v1.0.3 lowering Jetragon's technology unlock from level 79 to 70, plus the 1.0 launch raising the player level cap from 65 to 80. Pushing towers first, then field bosses, then the World Tree saves the most time.
