Fierce Fighter/Flighty Fighter Achievements in 1 playthrough

[MonkeyD]

At the start of the Finale Chapter, you will get a quartz reward,

one if you have fought 300 battles without running away
one for running 300 times from battles

each will reward you with and achievement.

Despite ppl will tell you to do a NG+, you can get both achievement in 1 playthrough.

Simple reach last boss of chapter 7 without running away from any battle and fighting at least 300.
Do a separate save, and just stay afk on the mirror before the final chapter boss and keep run away, engage run away repeat till you flee 300 battle(put swiftness quartz on to be sure to get a preemptive strike), beat Weissmann and go check the fountain to get the Reflect quartz.

Reload the save before doing the 300 running away process, kill chapter 7 final boss and get Mirror quartz instead.

There a map, the mirror is on the zone before the orbment station.

Hmm, but you still cannot get the rewards in one run. At least like this you can get the achievement.

Yea just for the achievements.
Also be aware that trying to reflect Cassius Armor Rend with Mirror quartz in the nightmare arena, will freeze the game.
