The Wicker Man bonus round rule is one of the many rules that can be applied during the Bonus Round episodes. It can be offered on any floor for any character but is more likely upon entering floors 2 or 3, as long as a certain counter counting ice enemies is reached:
When this counter reaches 5 or more, this rule has a chance to come in play. In short, large amounts of ice enemies allow this rule to come into effect.
The rule cannot appear at the same time as the Warlock Bonus Round rule.
When the rule activates, the status effect Frozen changes to Frozen?, which causes the values of all dice to reduce by 1 at the beginning of the turn. This effect applies to both fighters.
