Cookie Run Kingdom Beast Raid guide: Best cookies to use in Key to the Heart Challenge Mode cover image

Here is a guide on the best teams for Challenge Mode of the Key to the Heart Beast Raid in Cookie Run Kingdom.

The Challenge Mode for the Key to the Heart Beast Raid in Cookie Run: Kingdom is currently ongoing. This higher difficulty puts your cookies to their limits with a much tougher boss that packs quite a punch. On top of that, the boss deals true damage, so damage resistance will not help you much.

I’ll be real with you, Challenge Mode difficulty is for end-game players. You will struggle a lot to clear this without near-maxed-out lab upgrades and cookies. But if you want to try your luck, here is a guide on which cookies you need to invest in to clear the  Key to the Heart Beast Raid in Cookie Run Kingdom.
