Paimon's Bargains is one of the few places in Genshin Impact where you can trade deterministic currency for a specific character or weapon: duplicate pulls auto-convert into Starglitter and Stardust, and a fixed character/weapon pair goes on sale every month. This guide covers both currencies, who is on rotation, and what is actually worth buying.
Open Paimon Menu → Shop → Paimon's Bargains. It sells fixed items plus rotating characters and weapons, all refreshing on the 1st of each month at 4:00 server time:
The two currencies never mix: Masterless Starglitter comes from high-rarity duplicates and buys characters/weapons; Masterless Stardust comes from 3★ items and buys pulls plus ascension materials.
Duplicate pulls auto-convert with these rates:
| Duplicate pulled | Starglitter | Note |
|---|---|---|
| 4★ character (C0–C5) | 2 | 5 once the character is C6 |
| 4★ weapon | 2 | flat rate |
| 5★ character (C0–C5) | 10 | 25 once C6 |
| 5★ weapon | 10 | — |
| 3★ weapon/character | — | converts to Stardust (~15 each) |
A typical ten-pull yields about 4–8 Starglitter and 300–400 Stardust. Fully F2P, expect 10–20 Starglitter per month; reaching 34 takes 2–3 months of saving, so every purchase should count.
The pairs repeat on a fixed cycle — each duo returns 6 months later, so missing one is not a year-long wait:
| Months | Characters (34 Starglitter) | Weapon set (24 each) |
|---|---|---|
| January / July | Fischl · Xiangling | Blackcliff |
| February / August | Beidou · Noelle | Royal |
| March / September | Ningguang · Xingqiu | Blackcliff |
| April / October | Razor · Amber | Royal |
| May / November | Bennett · Lisa | Blackcliff |
| June / December | Barbara · Kaeya | Royal |
Right now (September): Xingqiu and Ningguang are available for 34 Starglitter. If you still lack Xingqiu, this is one of the best months of the year to spend — he is the irreplaceable Hydro enabler for Vaporize and Freeze teams. Weapons this month are the Blackcliff series.
Starglitter is scarce, so decide with this ladder:
| Tier | Target | On sale | Why |
|---|---|---|---|
| 🥇 Top | Bennett C1 | May / November | Removes the 70% HP cap so his ATK buff always applies |
| 🥈 High | Xingqiu (then C6) | March / September | Grab the base copy first, then chase C6 |
| 🥈 High | Xiangling C4 / Fischl C6 | January / July | C4 extends Pyronado 40%, C6 adds Oz coordinated attacks |
| 🥉 Situational | Blackcliff weapons | Odd months | Transition CRIT DMG sticks; the polearm is the most useful |
| ❌ Skip | Amber/Lisa/Barbara/Kaeya cons | Even months | The standard banner will hand them to you; low team value |
Rule of thumb: ask “do I actually use this character?” before “will the standard banner gift me this?” Spend 34 Starglitter only on units your teams genuinely need.
The winning play is “check the calendar, then strike”: before each 1st-of-month reset, look up that month's duo — Bennett C1 and Xingqiu months are your two most important spending windows of the year. Keep buying monthly Fates with Stardust, never burn Starglitter carelessly, and this little shop becomes a reliable constellation source even at zero spend.
