Accuracy Sphere
The guide lists an Accuracy Sphere as adding 4 Accuracy and associates it with the Hornet Arena fiend.
How it works
The guide’s stat table gives Accuracy Sphere a +4 Accuracy increase and lists Hornet as the associated fiend. It says Hornet is unlocked by capturing four of each Wasp-type fiend. The supplied passage does not explain the sphere’s use cost or how Accuracy affects battle calculations.
