Some impressions on party members:
Hero: terrific tank in PK mode with IGP (very expensive in honey terms though). Indirectly offensive powerhouse in WL mode thanks to Unity Force.
• Yeon: duh. After getting Rally I dumped Felix and made her permanent. Rally, Revive, Unity heal, all sorta offensive magic thanks to books. Only thing I missed from Felix is group AGI buff. Yeon is also kinda squishy.
• Gargan: dude/dudette got overpowered. Except for stun resistant/immune bosses like Barst I almost always use him. +5 TP for using Cape Stun? Hell yeah! Plus area stun. Then there's Coup de Grace. Don't forget Unity Force counter. That's insanely good against the Queen and her mooks. Sometimes I dump him for Bronwyn or offensive mage depending on situation.
• Bronwyn: except for Slenderman and mook-heavy boss fights I always use her in boss fights. Never found a boss (I think) immune to all her DoT attacks and Pinning Arrow. Didn't really feel she got nerfed one bit by +5 TP Pinning Arrow.
• Larelle: LQ makes her really strong. Starting to use her over Kyrie after finishing LQ and getting her item. I think by then she's better than Kyrie in mage-heavy parties thanks to MDF debuff. Plus later enemies tend to get resistant/immune to acid. Moxx item also gives her mana regen.
• Kyrie: still mainstay for mob clearing especially with golems/inanimate enemies. Not so hot anymore with AoE nerf and acid resists/immunities.
• Meline: also kinda weakened by AoE nerf. Censured still overpowered... when it works. Revelation still great for undead/vampire/werewolf/melee-heavy groups.
• Elaiya: great for Slenderman. Okay for magic reflect heavy mobs. Would be fantastic if Headshot works more frequently or more enemies you want to kill ASAP are not immune. I usually just bench her.
Felix is okay until I get Yeon. Doll is okay until I get Gargan or PK mode. The rest are kinda meh.
