Although Anthony Felix has only an E-rank degu amount, his ability which focuses on immobilization made him frightening to face. 'Paralysis Ball' and 'Fog Motion Sickness' both give an abnormal status to their opponents.
'Paralysis Ball', like its name, could paralyze an opponent one rank higher than him. While 'Fog of Motion Sickness' would make the enemies dizzy. It works as an AOE because of its nature as a fog that would spread into the surroundings and affect multiple enemies.
The enemies inside the fog would have a hard time seeing because of the obstruction of the fog. But the fog won't affect Anthony at all because he is the master inside the fog!
Of course, if a bloke had this ability, it would only look plain and simple but in the hands of Anthony, master of tactics and strategies, it would show a terrifying effect!
