Titan Temple Biome

Titan Temple came with Update 2, together with the Monster Egg and the Hungry Frog event. The wiki calls it the third-highest zone in the game, with a 7B Speed requirement and the third-rarest egg spawns. Its guardian is the Gorilla King, an Eternal worth $880M/s with a 9-hour egg.

Titan Temple's eight pets

• Spideron (Legendary, $95K/s, 4m) and Crustacia (Legendary, $130K/s, 6m). Crustacia is the top-earning Legendary in the game and Spideron ranks third.
• Bladehide (Mythic, $750K/s, 9m).
• Mantaris ($11M/s, 17m) and Rhinotaur ($17.5M/s, 29m), both Cosmic.
• Mutant Shark (Secret, $215M/s, 3h).
• Gorilla King (Eternal, $880M/s, 9h).
• Nightflame (Divine, $3B/s, 16h), fourth of the 14 Divines and the longest regular egg before Angels & Demons.

Where the Speed rewards break the pattern

Rewards here do not climb neatly with rarity. Spideron and Crustacia both pay +2.7m Speed and $13m. Bladehide, a Mythic, gives +4.8m, more than either Cosmic (Mantaris +3.4m, Rhinotaur +3m) and more than the Secret Mutant Shark (+4.1m). If you are farming Speed, Bladehide is the strongest mid-tier egg: 9 minutes for +4.8m, while Rhinotaur takes 29 minutes for +3m. Spideron has the best ratio overall, around 11,250 Speed per second of growth.

The road to Angels & Demons

Angels & Demons asks for 20B, a 13B gap, and Titan Temple's rewards (about 32.9M for one of each egg) are roughly the same size as Cherry Blossom's. Counting eggs only, that is about 1,900 Nightflames or 4,800 Spiderons, so the climb depends on equipment:

• Lucky Block Treadmill: +200 Speed per step for $75B, less than one Gorilla King reward ($88b).
• Secret Trail: 7× for $500B, under two Nightflame rewards ($300B each).

Monstrous mutation and the Rift

Update 2's Hungry Frog event ties back here: you bring parasite-infected eggs to your base, feed 5 parasites to the Hungry Frog for a Monster Chest, and those chests have a rare chance of the limited Monstrous mutation for monsters from Titan Temple. On the Shattered Rift sacrifice tiers, Spideron and Crustacia are Easy, Bladehide and Mantaris are Medium, and Rhinotaur is Hard.
