The Rat King is the king of the rats. He speaks in old English and is protective of his crown.

The Rat King can only do damage through poison, so shields won't protect against the Rat King.

However, most status effects that affect equipment and dice will greatly hinder the Rat King from using his equipment. Freeze make Rats need more dice, Lock prevents dice from being used, and Cursing equipment can cause him to waste his dice since it prevents the reroll.

While you won't take too much damage from the initial attack, each subsequent turn will cause you to take more and more damage, so this fight should be ended sooner than later.

In Parallel Universes, Curse? is more powerful since it basically grants you extra dice when you use it against him.

In the Reunion, Rat King has more dice and more opportunities to inflict Poison. However, since all his equipment is merged into one card, you can fully shut him down by using statuses like Curse.

However, Weaken isn't as powerful here because it still allows him to do damage and reroll the dice.

The Rat King's bio is obtained by completing all 36 regular episodes in the game.
