Herbest is the third evolution in the Fairy-Type Innocent Devil evolutionary development chart, but it can be the second evolution. They evolve from the Infant Fairy for 40 Axe/Spear/Special Evo Crystals, and thus, retain all of her abilities. The Herbest also has two new abilities not shared by the Infant's other evolution, the Leaffle: Antidote, which will heal all status abnormalities, and the upgraded version of Heal: Heal Lv. 2, which is useful in that it gives Hector 50 HP instead of 20. It evolves into Killer Bee and Hornet.
The following table represents the stat gain per level of the Herbest.
