Ginormo Sword

What level were your strength/sword to kill the "final" (area 16) boss? I'm having trouble taking it down and my sword is level 1400 or so and I have about 300 strength.

 Doppelganger tip

If you use an elemental armor that matches your weapon (eg. fire resistant with fire weapon) and go with as weak as possible armor (level 1 preferable) then he dies much more quickly)

[edit] 15 minutes to take down a 4th stage Slime and it only dropped 110 million I've had better from lower (Clay Golem level) stuff.

The final final boss

 Spoiler

is extremely hard, if not, impossible without hyper armor

Be sure to get that if you haven't already (It drops from 4th level living armor)

For the final area boss, make your sword small to kill it (It'll still take a while but it's attacks will be smaller)
