I had 47k power when I cleared it. Naruto is still Gold +3. Ino and Shikamaru are Red +1. Video link: https://youtu.be/u_7IDxvzvsU PS: Sorry you can't see my cursor focus, since this was recorded through the built-in replay.
Formation and masteries as below:
Red color : Enemy Shinobi Green color: Your Shinobi Summons: Dog of Hell or Ninja dog. More times your Scarlet Blaze ignites the opponents, the faster you can take them out.
Round 1: After Naruto's Combo, Scarlet Blaze mystery -> Sasori Round 2: After Naruto's Combo, Shikamaru mystery -> Ningendo Round 3: Naruto mystery -> Kimimaro Ino mystery -> Sasori Round 4: Nothing Round 5: Naruto mystery -> Kimimaro Scarlet Blaze mystery -> Ningendo Shikamaru mystery -> Ningendo / Choza Round 6: Ino mystery -> Choza At this point you should be able to finish.
