The Rat King bonus round rule is one of the many rules that can be applied during the Bonus Round episodes. It can only be offered on floor 2 for any character. The rule cannot appear while the Lady Luck rule (AKA hard mode) is active.
Rat King | Add two super enemies. |
When the rule activates, two super enemies will appear in the dungeon. One will be a Super version of a level 1 enemy on floor 2, and one will be a Super version of a level 2 enemy on floor 3.
The Bonus Rounds don't usually have super enemies, so this rule and the Frog rule are the only ways to face super enemies in the Bonus Round.
