I've got just 2 things that I haven't found an answer to in the game. Despite the effort. So, maybe someone here can help me.
1) How/where do I get the "Sacrifice" booze for the Quest #3?
2) How/where do I get/activate the Quest #12 (something about a Magic Mirror)?
I use Remy extensively too. Because of her unique double attack. Mine does 8x normal attacks, using a combination of "Speed Expert" and "Faster than Light!" illuminas. That and I was maxing her critical chance bonus and agility/attack from the start. So fast immense damage inflictor, with rapid critical hits.
That and her support abilities can be pretty clutch too, with high agility and double actions (the shield thingy and the mass heal).
Sacrifice is in the cooler at the squad six house. I guess the game expects you to think "Hey, Remy's a drinker, maybe she has it in stock" and check the house.
Quest 12 is set in the garage shop, and I think only available during chapter 5.
Funny enough, I didn't use Remy a lot until end-game where I final got good, high value illumina. But everyone had their uses to me; Rei to set up group damage by Attributes and/or stealing, Akari for Aegis and some single healing, Satsuki for power/magic buffing/debuffing, healing and Shooting Star, Konoha for self attack boosting and major Attribute attacks, Nana for her big magic damage, Kenshin for going berserk... Remy always felt the odd one out for me for being so situational (scanning, magic reflection, status effect kisses, ect). and regulated to help steal a few times because of her natural high luck. Eventually I too embraced her dual attack capabilities, which seem to overshadow her attribute attacks completely. Couldn't they get double attack too at least? Or higher damage values?
