Gems are the altar currency. Gold is the dungeon and merchant currency. Raidium is the endgame material used for corrupted immortalize. They are not interchangeable.
Where gems come from
- The experience page says quests pay gems that you roll in the lobby.
- INVASION is the code in the current description. An October 16, 2026 archive records 250 Gems.
- Premium is listed as 50% more AFK gems, 10% more gold, and 10% more XP.
- A July 2026 dungeon page says Infinite wave 15 pays 10 gems when the run ends, if your inventory has space.
Altar prices
Both the element database and a mid-2026 element page use the same prices: 100 Gems for one pull and 1,000 Gems for ten pulls. Sus Vampire takes gold on a three-hour cooldown and is described as an alternate Mythic chance. Purple dungeon chests can drop an element orb.
Banner percents that do not add up
A mid-2026 rate table prints these figures on one banner:
| Printed group | Names on that row | Printed rate |
|---|---|---|
| Rare | Fire, Water, Earth, Air, Nature, Sand | about 26% each slot |
| Epic | Light, Lightning, Ice, Smoke | about 10% each slot |
| Legendary | Angel, Dragon, Gravity, Lava, Darkness | about 2% each slot |
| Mythic | Kitsune, Phantom, Reaper, Galaxy, Mech, Nightmare, Astra | 0.25% each slot |
Six rares at 26% each would be more than 100% by themselves. Four epics at 10% would be another 40%. Treat 0.25% per named Mythic as the only figure that can sit on a normal banner without breaking the total. The larger percents may be group rates, or the word "each" may be wrong. Do not plan a gem budget on 26% for Fire.
Time is described as a Secret element on a limited banner, not on this standard table. Bunny, Fools Phantom, and Sunlar are described as event exclusives. Krampus, Infinity, and Solar are grouped as Mythic on a second roster table without the 0.25% figure repeated.
How to spend the first gems
- Redeem active codes before the first roll.
- A December 2024 tips video says codes can give Lucky Potions and that those potions should be used before a bulk roll, not before a single 100-gem spin. DONTDOUBTDAKID, now expired, was the code tied to a Normal Lucky Potion.
- Keep a Rare that can clear Ancient Tomb. The October 2026 ranking calls Nature the best Rare and Fire the easiest starter. Rolling past a working clearer is optional.
- A ten-pull is 1,000 Gems. Use the Mythic slot calculator if you want the independent-trial math for 0.25% per pull. It does not model potions or Sus Vampire.
The same 2024 video's pick of "best Mythic" was Kitsune for content outside Angel Sanctuary, and it warned that endgame picks change. The October 2026 board still places Kitsune in S, next to several elements that video did not rank.
