Mysterious Acorn

F+1 'Acorn', and Theurge (Tier-15) and Alchemist (Tier-15) to a very small area (10-meter burst, 1-hour cycle)!

Booster for your pets (the fairies in particular)! It’s significantly more potent than most of the existing boosters, and acts as warming stones (increases mating speed), a longevity pool (makes your pets live longer), and has a handful of mutational boosters to give you a better chance at getting those special pets.
