How do you find ninja warz bosses?

Answer 1

At specific levels, the bosses would appear on an island for you to fight.

Heikinteki Josei or School Girl, is the first boss you will encounter. Heikinteki Josei has 350 health. You will get a lunchbox (8.93 dps, faster) and 5 karma for defeating her.

The next boss appears at level 15, and it is Genbu. It has 2600 health. You will get a relic "Genbu's Scale" (+10% critical hit chance and +8% attack speed) and 10 karma after defeating it. If you defeat it with food weapons, you will gain an additional 10 karma.

At level 25, you meet Tondeiru Josei, a small child with a big sword. After defeating her, you will earn 10 karma and earn a Daikatana (20.14 dps, normal). If you fight her again and deal the killing blow with her own sword, you will gain 10 karma.

The final boss, at level 35, is Mecha-Genbu. It has 35000 heath, so watch out! When you defeat it, you gain 10 karma. If you defeat it after it launched its nuke, but before it lands, you gain 10 karma. If you defeat it after it launched its nuke and it lands, you gain an additional 10 karma. After defeating it, you earn a Laser Visor (40.5 dps, normal).
