Two currencies on the screen
The coin of the world you are standing in shows on the left, under your Diamonds. Coins pay for areas and normal eggs. Diamonds are the separate currency used for merchants, many rebirth rewards, and some machines.
World coins do not stay useful when you change worlds. Spawn World coins do not buy Tech World eggs.
Denominations
Each step below is one million of the previous unit.
Spawn World uses Coin, Gold Bar (1 million coins), Platinum Coin (1 million gold bars), Platinum Bar, Emerald Coin, Emerald Bar, and Sapphire Coin.
Tech World uses eight currencies starting at Tech Coin, then Tech Bar, Tech Gold Coin, Tech Gold Bar, Tech Platinum Coin, Tech Platinum Bar, Tech Emerald Coin, and Tech Emerald Bar. Each listed step is one million of the one before it.
Void World, as of the Update 41 currency note, uses Void Coin, Void Gold Bar (1 million Void Coins), and then Void Platinum Coin and Void Platinum Bar. The platinum-coin row is priced in Void Bars. That excerpt does not print a separate rate line for a Void Bar, so that rate is left blank here.
Fantasy World uses Fantasy Coins. A full Fantasy denomination ladder was not in the excerpt.
Blood Moon adds Candy for event eggs, Spooky Wands for the five new upgrades, and Season Tokens for the Season Pass. Those are event items, not a new world coin.
Diamonds potions
Standard potions stack. Combine them in the Upgrade Potions Machine in Area 13, Dark Forest. They drop from breakables, chests, spinny wheels, merchants, daycare, vending machines, minigames, and gifts. The Diamonds line also lists secret rooms.
| Diamonds potion | Effect | Duration |
|---|---|---|
| Basic | +10% Diamonds | 10 minutes |
| Rare | +25% Diamonds | 20 minutes |
| Epic | +40% Diamonds | 30 minutes |
Higher Diamonds tiers exist. A collection page lists Diamonds IX at +100% for 1 hour 30 minutes. Tiers between Epic and IX are not copied here because the two sources were not read as one continuous table.
The basic Coins potion is listed at +20% coins for 10 minutes. Damage potions scale by tier. Two celestial damage entries are +150% for 1 hour 40 minutes and +165% for 1 hour 50 minutes. Luck potions raise egg luck and, in the potion overview, do not apply to exclusive eggs. Their tier percents are not listed because the tier table was incomplete.
Diamonds enchant
Enchants are books you equip. Upgrade them in Area 16, Crimson Forest. The Diamonds enchant raises Diamonds from breakables:
| Rarity | Bonus |
|---|---|
| Basic | +10% |
| Rare | +20% |
| Epic | +30% |
| Legendary | +35% |
Happy Pets, an Epic enchant, gives pets random bursts where they move 25% faster and attack 40% quicker. A Coins enchant line and a Treasure Hunter line exist for coins and item drops. Their tier percents were not in the excerpt, so they are not invented here.
Where Diamonds come from without a guess at the rate
Rebirths 1 through 4 pay 10,000, 25,000, 50,000, and 100,000 Diamonds. Exclusive Daycare in Area 145, Egg Incubator, takes Huge and Titanic pets and pays Diamonds. The rate is not published in the machine blurb, so this guide does not invent a diamond-per-hour number. Free-diamond stops exist, including one in the Castle, and they are small next to a rebirth reward.
What not to do
Do not treat a video's gem-selling link as a game system. Do not type your Roblox password into a site that promises Diamonds or Huges.
