The four spells he chose were a 2-Star Ice Spell Ice Projection, 3-Star Ice Spell Ice Dispersion Body, 4-Star Neutral Spell Arrow Rain, and 4-Star Neutral Spell Magical Wave Emission.
And Bonkey took the liberty to convert them to suit the bonk.
Skill: Bonk Projection - 10 Bonk Bites
Effect: Creating multiple Bonk Bats in the air that could act as a footing in the air or a trap that slows down the enemy's pace.
Skill: Bonk Dispersion Body - 34 Bonk Bites
Effect: By infusing the body with Magic Power, the body could turn into ice crystals. The Bonk Bat will become the main body inside the ice crystals.
Skill: Bonk Rain - 86 Bonk Bites
Effect: Creating a Magic Circle that summons multiple Bonk Bats to rain in a certain area.
Skill: Bonk Wave Emission - 91 Bonk Bites
