Eternal Lunar Dragon income by mutation

At base weight (60,000 kg). With two mutations the wiki disagrees with itself on whether they add or multiply, so both are shown.

MutationIf they addIf they multiply
None$250M/ssame
Silver$300M/ssame
Golden$625M/ssame
Rainbow$875M/ssame
Golden + Bloom$687.5M/s$781.25M/s
Rainbow + Parasite$1.38B/s$2.63B/s

Worked example: a Golden Eternal Lunar Dragon at twice base weight

  1. Weight ratio: 120,000 kg ÷ 60,000 kg = 2.
  2. Size multiplier: 237/60 = ×1.5333.
  3. Golden multiplies by 2.5, so income = $250M × 1.5333 × 2.5 = $958.33M/s, which is $3.45T per hour.
  4. Saving for the Lucky Block Treadmill ($75B) from $0 with only this pet: 1m 18s. A plain Eternal Lunar Dragon at base weight would take 5m 00s.
