to kill the medic boss u need 2 skills: subversion and shatter bolt. they can be found in the bottom right hand corner of the ability page. So during battle take down his health until it is near 990,000. Then use the shatter bolt to stun him for 2 rounds . Now use subversion and then keep pressing the 'I' until he uses his heal ability. he will kill himself. hope thid helped :)
