What is the best way to raise your HQ to 999? I'm in the endgame with multiple character's stats at 99,999,999, and I need the high HQ to more efficiently boost the stats of a few low-stat items to the cap.
Take your Vita with you when you go out. Farming Ordeal Room 4 can get me to the 400s, but if I leave my Vita on as drive around to run errands or visit friends or family will temporarily boost me to the 600s. I'll be traveling some 250 miles next week... I suspect I'll finally hit the fabled 900.
I'm raising all of Barefoot X's stats. I've got one of each of the stat-boosting innocent in the shoe excepting speed, and a second innocent which I occasionally switch around to give myself a slight bonus each time I defeat the Item God.
At 380 HQ (which is about the highest I've ever gotten it) I get a stat boost of 129 for each innocent in the item. I'm up to 60K for each stat (about four hundred and fifty-odd gencies), and have long since maximised speed.
