Look, here's what I did.
DON'T KILL THE MARLBORO! It's not worth the effort.

1. Junction 100 berserks to status defense. this is the MOST important. If you're entire party is berserked AND confused, there's no hope.
2. Junction confuse too if you can. if not just be sure you have berserk and wait until you are hit (if you make it that long)
3. heal if you want
4. MUG the marlboro for tentacles. You can get them by mugging, sometimes they don't even drop tentacles so its so much easier.
