Since I love the weapon Casey, I decided to make a character around it. I came up with the Batter.
What the Batter starts with:
Casey - a melee weapon that increases curse by 2. Swinging the bat after a long charge-up will damage nearby enemies and reflect nearby bullets. The bodies of enemies killed by the bat will be launched and can damage other enemies.
Striped Jersey - Provides immunity to enemy contact damage and increases movement speed by 1.
