Carbon Dog / Diamond Dog ( Battle )
This is a TWO PART battle.
1) Carbon Dog - Have Paula and Poo cast their highest level Freeze spells as often as possible. Be careful with Jeff's Multi Bottle Rockets because if Carbon Dog is defeated before the Multi Bottle Rocket is set off, it could hit the Diamond Dog and since he has a power shield it will reflect back causing certain death.
2) Diamond Dog - If you can use a Shield Killer or Neutralizer to take down his Power Shield that will free you up to use Multi Bottle Rockets. Otherwise just throw as much PSI at him as you can until the battle ends. Watch out for his Flash Ω which can paralyze you or even kill you ( unless your character has a Night Pendant or Sea Pendant equipped ).
