How Mammoth compares
Neighbors by income in Snow (5 of 8):
Other Mythic pets
Mammoth guide
Two tonnes is the Mammoth's base weight, by far the heaviest among Snow's Mythic and Legendary pets. On income it leads the biome's Mythic pair at $42K/s, ranked 18th of 23 Mythics and 143rd of 198 overall.
Mammoth Egg
- Grow time: 5 minutes
- Reward: +19.2k Speed and $4.2m
- Base weight: 2,000 kg
A 5-minute egg lines up exactly with the 5-minute nest reset the wiki describes, so a Mammoth slot turns over once per cycle. The +19.2k Speed is the largest reward of any Mythic in the first five biomes.
Between the Sabertooth and the King Mammoth
- Sabertooth Tiger: $35K/s, 4-minute egg
- Mammoth: $42K/s, 5-minute egg
- King Mammoth (Cosmic): $400K/s, 15-minute egg
The Mammoth is 20% better than the Sabertooth for one extra minute. The King Mammoth earns nearly ten times as much for three times the wait, so if you can leave a slot alone for 15 minutes, that is the stronger choice. The plain Mammoth fills the role of a reliable once-per-reset earner.
Heavy base, heavy eggs
The wiki notes that larger eggs are heavier and slow you down while you carry them. With a 2,000 kg base, the Mammoth's size rolls are measured against an already enormous starting point, so a Mammoth that looks huge may still sit near its base multiplier. Estimates from the formula:
- Golden: about $105K/s
- Rainbow: about $147K/s
- 10 times base weight (20 tonnes): about $174K/s
- 100 times base weight: about $719K/s
- 200 times base weight: about $995K/s
- Rainbow at 100 times base weight: about $2.52M/s
The Mammoth appears in the Medium tier of Riftborn sacrifices, so spare plain copies have a use when that banner is active.
