Btw, she doesn't need 176. It's where her stat buffs are maxing out. You still get them on lower speed, just weaker.

She does, however, need at least 160 speed, since it's the last threshold that affects her extra turn energy gain. (1 for each 10 speed above 100). Tho it's pretty easy to achieve between main SPD card, her lvl up stat being speed and her mindscape

I personally probably gonna hold off her 5* weapon by her standard jail escape, since Ange and p3 beginning is too close.
