Since everyone seems to have trouble with take no damage on 'Odd Job' I thought maybe I should help. Let me first say I was terrified of this level after reading how horrible this level was for most people. I thought I was going to have to spend at least an hour perfecting it. Turns out I got this on my very second try. The reason why I failed the first was cause I read some of the solutions above.
So here is the solution or the best technique strategy. Select the max level silvertail along with a max level hireman. EQUIP THE ANIMA DELFECTOR (I CANNOT STRESS HOW IMPORTANT THIS IS). Then Select the Mind and Agility Ampoule. As soon as the level starts move in circles around the screen to dodge all the fireballs. And dont worry so much about shooting the enemies, let your hireman do that for you. After you pass the first section switch over to your deflector. Hold down the deflector once you see ANY threats. Even if the enemy is small and you can kill it with one shot dont even bother. Do this for the next two sections (which is suppose to be the hardest parts) and finally when you reach the boss at the end use your hireman special. One special should do the trick and they should die before you enter in free flight mode, if not hit them with another one. Hope this helps
