The Bow is a gift from Kelt the second time the champion visits him. It can be used as a special attack against enemies. The more the champion trains with Kelt, the better their bow skill becomes.
Bow, when first gotten "Here," Kelt says, tossing you a spare bow. "You can use this, for right now. We train colts on it... you know, before their balls drop. Should be just about right for your level. Keep it if you want." Despite his mocking description, the bow he gives you really is a decent weapon. You take it up and start towards the practice field, Kelt following behind.
The bow will always miss or fail against the Worms, Isabella, or any enemy if the champion is Blinded. If Amily has been concentrating the previous turn, then she will automatically dodge the attack. Vala has a bonus 70% dodge chance.
Bow Skill maxes at 100, as shown on 'Stats' screen. Additional training with Kelt will show the stat above 100, but reset to 100 when the bow is used.
