A pure mind mag raised the regular way (giving it 3 items at a time without the need to bank it) would only be 5/0/0/185. To obtain 13/0/0/187, you need to bank the mag after every item (so 1 fluid at a time) from lvl5 to lvl35. So it's really annoying to make and takes forever.
That's why I wanna know if that extra 2 mind would really be worth more PDs (i.e. worth the trouble...).
