User blog comment:NemuriNoMori/blue x purple = trauma! The fight for IM SS/@comment-16397685-20130929194252

I completed and max out IM's skill with 7 of her mags in just 2 days without using a single item. The trick is that you need to know opponents that you can easily win. High DEF doesn't always mean they got a good defense team.

Maybe you need to form a good defense team to have the advantage on a SS battlefield. As I got Minerva as leader, not many people try to steal me and if they did, they would lose anyway.
