In Build a Ring Farm, the T-Rex made its emphatic debut with the game’s third major update. It used to be the only pet of Divine rarity before the addition of the Starfall Griffin. This pet provides the best earnings boost, while its passive allows it to remove a mutation from a crop and apply one with a better multiplier.
Here’s all you need to know about the T-Rex pet in Build a Ring Farm.
What does the T-Rex offer in Build a Ring Farm?
Like other pets, a T-Rex comes in three different sizes: Regular, Big, and Giant. The chance of getting a Big T-Rex or Giant T-Rex from the Dinosaur Egg is extremely low, but they give a better boost and passive compared to a Regular T-Rex.
At Level 1, a Regular T-Rex gives a 12x earnings boost. This buff is increased gradually with every upgrade made with Cash. You can enhance the critter till Level 50 to make the most out of it in your farm.
This Divine pet has a passive that lets it remove a mutation from a crop and apply one with a higher multiplier. For instance, it gives the Farm mutation to a previously Radioactive crop because the former has a 4x multiplier while the latter has a 3x multiplier.
Here are all the mutation changes made by the T-Rex:
- Wet to Frozen
- Frozen to Autumn
- Autumn to Void
- Void to Radioactive
- Radioactive to Farm
- Farm to Rainbow
- Rainbow to Cosmic
- Cosmic to Bubblegum
- Bubblegum to Fire
Similar to the Kitsune and Mammoth, the T-Rex can upgrade the mutation on a plant. The major difference is that it is guaranteed to apply a better mutation to a crop and raise its sale value, whereas the Kitsune and Mammoth have chance-based passives.
The Regular T-Rex, at its initial level, triggers its passive every five minutes. This time is reduced with every upgrade.
