Rolf - 2 Laser Knives until SWORD OF ANG which is powerful
Rudo - 2 Laser knives until Laser Cannon
Josh - 2 laser knives until 2 laconian maces (Kain's knife animation is.. messed up)
Anna - 2 slicers
But in the Dams.. here is how my party went:
Anna - Storm Gear for Gizan
Rudo - Laser Cannon
Rolf - knives until sword of ANG
Josh - Crystgear (to cast Gra) / knives if needed
So it comes down to Gizan, Rudo, Rolf, Gra. Takes out most everything in 2 turns.
Now when I found the GIRES heal gear, everyone got a piece so when healing is needed, everyone uses a GIRES item. Whoever heals up to max attacks the rest heal.
Now on the Nei Dungeons i switch it up.
Anna - Gizan
Rudo - Gun
Rolf - Sword of ang
Kain - Cryst or 2 laco maces
If the monster party is 3 or 4 of the same kind, Anna uses her slicers and KAIN uses stormgear.
When the monster group consists of 2 types of monsters like 2 Firgammas and a wireface, ANNA using Storm gear for Gizan is better.
Until healing items, everyone carried 5 trimates.
I just wish defense helped in the Nei Dungeons x.x Those monsters hit TOO tough.
