sorry i couldn't find anywhere where the boss health was listed for the level 100, so i thought i would share the boss health with you.
I am level 68 with 6.7m raw attack and it took 18 hits to bring boss level 100 down which is around
120million health. i used the 13 hit method and 20 gold to get the prize. the 20 gold for level 100 was the only gold i had to use.
I am on level 81 boss with my main and will post the boss health for level 100 when i am done. My main is level 123 with 10.5m raw attack.
