How to roll Battle Charms
Reach Rebirth 2
Grow a chicken fighter battle charms stay locked until Rebirth Level 2, so clear your first two rebirths before spending anything on Charm Dust.
Open the charm menu
Go to your Flock, select the chicken you want to charm, then click the plus button on the left side to open its Battle Charm menu.
Spend 20 Charm Dust
Hit ROLL CHARMS at the bottom of the menu. Each roll costs 20 Charm Dust, so the free 100 daily from the Shop covers five rolls.
Lock what you want
Lock a slot once it shows the stat you want โ locking stops that slot rerolling, but every lock doubles the cost of rerolling the rest.
