As you progress your characters (around level 32) you will gain a tech 3 attack that covers a large area attacking many foes sometimes multiple times at once on each enemy. Begina's Crescent Edge, Culcha's Orc feast...meat...toss...something , and Orochimaru's Dragon attack are 3 that will help you get this easily. If you open with Begina's, on 5 targets simultaneously, you will get an Eighty Five hit combo. Use your teamwork attack to control Culcha or Orochimaru and follow with their tech 3 attack. These will fill your battle gauge quickly as well as fill your BF attack bar allowing for a powerful finisher almost always doing more than 15k damage from just culcha and begina and 125+ hits.
