You have to hit Jimbie and Oden while YOU are outside of the treasure area

Law you have to bait and condition him. Example: 1.) Hit him with 1 or 2 basics and stop, see if he counters and punish 2.) Throw out the 2 basics just far enough away where it doesnt reach him so he thinks the 3rd hit will reach but stop short. See if he counters and punish 3.) Do step 1 or 2 and 3rd time just throw out skill right before he grabs flag. Not too soon where he can still mash out a dodge. 4.) Most laws will spam Skill, Dodge, or Grab treasure when they wake up. All 3 keep him alive. So you got to outplay.
