Eternal Lunar Dragon guide
Seven hours is a long time to leave an egg in your pen, and the Eternal Lunar Dragon is the pet that asks for it. In exchange it earns $250M/s, the most of any Cosmic biome pet except the Divine Unicorn.
The Eternal Lunar Dragon Egg
- Biome: Cosmic, 9th in the biome order
- Entry requirement: 700M Speed
- Guardian: Cosmic Skeleton
- Grow time: 7 hours
- Hatch reward: +1.9m Speed and $25b
- Base weight: 60,000 kg
The $25b payout clears the price of the Galaxy Trail (20B, 5×) on its own, so a single hatch can fund that upgrade.
Compared with the dragon below it
The Cosmic Dragon, the zone's other dragon, earns $60M/s from a 3-hour egg. The Lunar Dragon earns a bit over four times as much for a little over twice the growth time. For someone who plays in long sessions or leaves the game running overnight, that ratio favours the Eternal.
Against the previous zone's Eternal, the Mosasaurus ($180M/s, 6 hours), it is about 39% stronger for one extra hour.
Rankings
- 2nd of 8 in Cosmic
- 19th of 24 Eternal pets
- 143rd of 198 overall, counting from the lowest earner
Potential with mutations and size
At 60,000 kg base weight, big copies of this egg are heavy to carry, and the wiki notes that heavier eggs slow you down. Estimates from the formula the wiki documents (marked beta there):
- Golden: about $625M/s
- Rainbow: about $875M/s
- 10× base weight: about $1.03B/s
- 100× base weight: about $4.28B/s
- 200× base weight: about $5.92B/s
- Rainbow with 100× weight: about $15B/s
A 10× copy would already outearn an unmutated Unicorn.
