Boss 18 First of all, make sure that Tolten, Seth, and Kaim are in your party and all have Machine Killer Lv 2 or 3 rings on them -- Hacker and Lotus work. Assuming you have the right equipment, you'll need to know your opponent's offense. The Kakanas Tank will ram single characters for a few hundred damage, while the Cannon will hit everyone for a few hundred damage. The Support Tanks have weaker attacks of their own as well, but will occasionally sap your MP to charge the Kakanas Tank (left) or Kakanas Cannon (right). Now the powered up tank hit isn't too bad -- still only 500 damage or so. A Full Charge Cannon will wreck your whole damn team for 1,000 or more. Because of this it is recommended you immediately target Support Tank B.
