Merchants are the only way to buy many of the best items in Sol's RNG. They sell potions, Runes, Void Coins and talismans that cannot be crafted or rolled, but they stay only three minutes and the next one can take up to 45 minutes to arrive. This guide covers who the merchants are, how often each appears, what each sells at which price, and how to catch one before it leaves.
Everything below comes from the Sol's RNG wiki's pages for the merchants and their items. Prices are in coins ($) for Mari and Rin, and in Dark Points (P) for Jester.
How merchant spawns work
Merchants were added in the Era 8 update. A merchant spawns every 15 to 45 minutes, and the wiki gives the odds for who shows up:
| Merchant | Chance | Beam of light | Sells |
|---|---|---|---|
| Mari | 80% | Colossal white beam | Potions, Gears, Lucky Pennies, Void Coins |
| Rin | 10% | Orange or yellow beam | Talismans |
| Jester | 10% | Purple beam | Runes, Heavenly Potions, Oblivion Potions, tracker |
Every arrival comes with a loud horn-like sound and a chat message such as "[Merchant]: Mari has arrived on the island...". A merchant leaves three minutes after arriving.
A detail from the wiki: while a merchant is on the map the spawn timer is paused. After the merchant leaves, the wait is a fresh 15, 30 or 45 minutes, not 12, 27 or 42. That is why many players rejoin a private server when hunting for merchants.
Mari always appears close to the main island's spawn area, while Jester spawns mostly around the edges, and Rin appears near the Stats board.
Finding a merchant fast
- Merchant Teleporter. Costs 40 Robux in the Gamepass Store, has no cooldown and teleports you straight to the merchant. If none is on the map it shows "There's no merchant spawned."
- Merchant Tracker. Costs 1,000 Dark Points from Jester. It marks any spawned merchant with an icon (a backpack for Mari, two masks for Jester), even in the Cave or the Limbo. It is off by default every time you join. The wiki calls it the only item you can buy from Jester that can be used infinitely.
- Using both. The wiki's suggestion: have the tracker tell you when someone has spawned while you are away, then use the teleporter before the three minutes run out.
Mari: potions for coins
Mari is the common merchant. She sells for coins, and the stock refreshes with each visit.
| Item | Max stock | Price |
|---|---|---|
| Lucky Potion | 25 | 1,000$ |
| Lucky Potion L | 10 | 2,000$ |
| Lucky Potion XL | 5 | 4,000$ |
| Speed Potion | 25 | 2,000$ |
| Speed Potion L | 10 | 4,000$ |
| Speed Potion XL | 10 | 8,000$ |
| Mixed Potion | 25 | 3,000$ |
| Fortune Spoid I | 4 | 4,000$ |
| Fortune Spoid II | 4 | 6,000$ |
| Fortune Spoid III | 1 | 8,000$ |
| Gear A | 1 | 10,000$ |
| Gear B | 1 | 10,000$ |
| Lucky Penny | 3 | 77,777$ |
| Void Coin | 2 | 500,000$ |
Gear A, Gear B and Lucky Pennies are used to upgrade the Bank. The wiki also lists Rainbow Syrup at 3,000$, but its stock is marked unobtainable. A tip from the wiki: if your daily quest asks you to collect Luck or Speed potions, buying them from Mari counts as collecting them. Our potions list has the effects of every potion, and the gears page shows what Gear A and Gear B fit into.
Because Mari makes up 80% of arrivals, the most common visit is a shopping trip for Lucky Potions. The luck guide explains how those stack.
Jester: Dark Points and rare items
Jester does not accept coins. You first exchange biome-exclusive items, Void Coins or Stella's Star for Dark Points, then spend the points. He has only a 10% chance to appear, so check the name in the chat message.
The wiki lists these exchange rates for items you hand in:
| Item you sell | Dark Points |
|---|---|
| Icicle, Wind Essence, Rainy Bottle | 1P each |
| Stella's Star | 3P |
| Hour Glass | 7P |
| Eternal Flame | 13P |
| Piece of Star | 15P |
| Feather Vial | 16P |
| Curruptaine | 18P |
| NULL? | 27P |
| Void Coin | 250P |
And these are the items he may stock:
| Item | Price | Stock |
|---|---|---|
| Lucky Potion | 1P | 45 |
| Speed Potion | 2P | 45 |
| Random Potion Sack | 10P | 10 |
| Strange Potion I | 15P | 25 |
| Strange Potion II | 25P | 25 |
| Stella's Star | 5P | 1 |
| Stella's Candle | 50P | 5 |
| Rune of Wind, Frost, Rainstorm | 50P each | 1 |
| Rune of Hell | 300P | 1 |
| Rune of Galaxy | 375P | 1 |
| Rune of Corruption | 450P | 1 |
| Potion of Bound | 500P | 1 |
| Rune of Nothing | 650P | 1 |
| Heavenly Potion | 1,000P | 1 |
| Merchant Tracker | 1,000P | 1 |
| Rune of Everything | 3,000P | 1 |
| Oblivion Potion | 5 Void Coin | 1 |
Because biome-exclusive items feed Jester's economy, it helps to know which biome drops what; the biomes guide covers that. Selling a Void Coin gives 250P, while Mari sells it for 500,000$, so the coin is a convenient bridge between the two merchants.
Rin: talismans and trials
Rin sells talismans for coins, and each one after the first two requires finishing a quest with the one before it:
| Talisman | Price | Unlocked by |
|---|---|---|
| Sunstone Talisman | 100,000$ | Available |
| Moonstone Talisman | 100,000$ | Available |
| Day and Night Talisman | 250,000$ | Reach Daytime with the Sunstone Talisman equipped 10 times and Nighttime with the Moonstone Talisman equipped 10 times |
| Overtime Talisman | 500,000$ | Reach Daytime and Nighttime 30 times each with the Day and Night Talisman |
| Soul Collector's Talisman | 1,000,000$ | Reach full stacks with the Overtime Talisman |
| Soul Master's Talisman | 1,500,000$ | Collect 10,000 stacks with the Soul Collector's Talisman |
Rin's second trial ("Time forever runs forward") is a slow quest. When asked about progress, her dialogue says it "will probably take about a month." Because she appears only 10% of the time, plan on a long chain.
Limited merchants
Jack the Pumpkin is a limited merchant added in Eon 1-1 during the 2024 Halloween event. He sells items such as Pump King's Blood for Pump Tokens, which you get by exchanging Halloween-exclusive auras and pumpkins. The wiki calls him the first and only limited merchant. Mari's page also names Fischl as another merchant NPC, but the merchant pages do not describe his stock, so he is left out here.
Common mistakes
- Waiting for Mari to restock. She stays only three minutes.
- Spending coins on Jester's items. He only accepts Dark Points, and Oblivion Potions cost Void Coins.
- Selling every Void Coin. Mari sells them for 500,000$ and Jester's Oblivion Potion costs 5 of them; know what you need before you trade.
- Leaving the Tracker on its default. It starts off every time you join.
- Forgetting the daily quest. Potions bought from Mari count toward potion-collection quests.
