Mantaris guide
Mantaris earns $11M/s from a 17-minute egg. Put that next to the Koi from Cherry Blossom, which earns $12M/s from a 25-minute egg, and the Mantaris delivers almost the same income eight minutes sooner.
Mantaris Egg details
- Biome: Titan Temple, 11th in the biome order
- Speed to enter: 7B
- Guardian: Gorilla King
- Grow time: 17 minutes
- Hatch reward: +3.4m Speed and $1.1b
- Base weight: 1,500 kg
Choosing among Titan Temple's mid eggs
The three eggs in the middle of the zone each do one thing best:
- Bladehide: 9 minutes, +4.8m Speed, $750K/s (best Speed per egg)
- Mantaris: 17 minutes, +3.4m Speed, $11M/s (balanced)
- Rhinotaur: 29 minutes, +3m Speed, $17.5M/s (best income)
Mantaris earns more than fourteen times the Bladehide, and the Rhinotaur earns about 59% more than Mantaris but takes twelve extra minutes and gives less Speed. For a player who checks back every quarter of an hour or so, the Mantaris is the middle ground.
The $1.1b reward covers the Red Trail (750M, 4×) with money to spare.
