Rereading my own post, maybe it's confusing? It definetly would be for someone who didn't play the game.
No matter.
As mentioned and now I'm back home, I've passed Aqueducts and am playing the game as I play other games, sidequests first, main quests next to open more sidequests.
Boosted all party members I could, this means I still can't power up Loki, Maddox, Zolean and Jager. Unlocked potential for everyone else. Including Caedmon with his three personal quests where in the end you meet the duo from that quest you mentioned, Eagle's Nest. But unlike the first time where I had to reload, here they were easy-peasy. It's the same old strategy as with other bosses, don't march to them, stand your ground and let them come to you.
Currently am on a sidequest The Assistant, it feels like another chore, but well.
This is how my party currently looks like (first character is union leader):
1. Rush, Baulson, Torgal, Zolean
2. David, Gabriel, Blocter, Gaou
3. Emmy, Caedmon, Roberto, Darien, Violet
4. Irina, Jager, Paris, Flenys, Allan
Reserves (and I don't plan to use them actually):
Pagus, Loki, Nora, Rhagoh, Leshau, Maddox, Kate
Pagus, Loki, Nora, Rhagoh and McGrady were in my party before, but newer recruits were simply better than them. Leshau, Maddox and Kate seem worse than McGrady so I didn't put them to use at all after recruiting.
Irina got Omnistrike unlocked that's why I've made her leader although she's somewhat lacking in other specs.
Total HP in all active units is near 5K. I plan to break them into 5 units when I can make 5 units of 5K HP each.
For all members I went balance route. Maybe it wasn't the best strategy, but I don't know:
- what difference does that choice make
- what new recruit I'll get
- if I recombine units, will they desperately lack of stat/skill
Not saying this was the best possible units setup I could make, but currently it works well. Means, I had to use resurrection (vivification) only once past aqueducts. Prior to aqueducts, my basic strategy was practically having 100/100 Relaxing Herbs and Restoreleaf. I didn't use them 24/7, but were needed in some boss fights and are dirt cheap (at least were to me after Mr. Diggs halfhour grind
).
