The Dire Wolf bonus round rule is one of the many rules that can be applied during the Bonus Round episodes. It can be offered on floors 4 and 5 for any character, as long as either of these conditions are met:
When the rule activates, the status effect Cursed will only activate 25% of the time, instead of 50% of the time. While this makes the effect on both fighters weaker, it also makes the status last for a longer time, since Curse only disappears when the effect is triggered.
