Equipped pets break crystals. That is the gold loop in the official description's hatch-and-upgrade cycle, filled in by community guides. Exotic crystals appear after Exotic Luck. Pets prioritize them, and they pay more than ordinary crystals. Higher exotic tiers are described as needing Rare Earth.
Exotic score
Community pages assign these exotic scores: Common 1, Uncommon 5, Rare 10, Epic 15, Legendary 25, Prodigious 50, Ascended 75, Mythical 100.
Official Exotic Crystal Hunter badges that were read directly use Exotic Crystal Score thresholds of 100, 1,000, 5,000, 25,000, 100,000, 500,000, and 1,000,000. The 100 badge is Novice Exotic Crystal Hunter. The later display names on that same page were not retained, so this site does not invent them.
What stays after rebirth
Community rebirth notes say Pet Score resets and Total Pet Score stays. Shop progress such as +1 percent Damage and +1 percent Drop Rate stays. Gold does not stay unless you own Gold Hoarder. That upgrade is described as 250 Mythic Stones and it requires 100 percent Drop Promotion Chance. Spend gold down before a rebirth if you do not own that upgrade.
A practical buy order
- Magnet, so crystals you break actually reach you.
- The next area you can already enter and farm.
- Pet slots.
- A fusion batch for the egg you can restock.
- Hatch speed, damage, and movement once the loop is stable.
- Shiny hunting when the zone gate asks for Shiny Score.
- Metallic hunting and a planned rebirth after you can afford the stone upgrades you actually want.
Official gold badges that were readable say Novice Gold Earner at 1,000,000 total gold, Intermediate at 25,000,000, Advanced at 200,000,000, and Prodigious at 1,000,000,000,000. Other gold-badge descriptions on that page were hashed and are omitted.
